This can make --forest work better. + +Supply better data for top's CPU state display. Currently top has +to subtract old numbers from new numbers and divide that result by +the number of processors. The kernel won't even supply the number +of processors in a portable way. + +Supply data for the ADDR and JOBC fields. + +Support & supply data for SL and RE. + +Add a /proc/*/tty symlink to eliminate guessing when /proc/*/fd is +not accessible. + +Add /proc/*/.bindata files to avoid string parsing. It should be an array +of 64-bit values on all machines. New entries go on the end and obsolete +ones get filled in with something logical -- entries must never be deleted! + +Add all the stuff Solaris has. This would also replace ptrace. + +---------------------- watch -------------------------- + +Tolerate VT100 line-drawing characters. Maybe translate them. + +---------------------- w -------------------------- + +The LOGIN@ column sometimes has a space in it. This makes correct +scripting difficult. + +Time formats are demented. + +---------------------- vmstat -------------------------- + +Extract /proc/diskstats parsing from vmstat into libproc somewhere. + +--------------------- libproc ---------------------- + +Stop storing fields with duplicate info (often different +units: kB and pages, seconds and jiffies) in the proc_t struct. + +Use own readdir code (assembly language) because glibc sucks ass. + +---------------------- top ------------------------- + +Share more stuff with ps. + +don't truncate long usernames + +have a --config option + +---------------- ps for now, maybe move to libproc ------------------ + +With forest output and a tty named /dev/this_is_my_tty, the position +of the command name gets messed up. (we print too many spaces) (fixed?) + +Fix missing stuff for these formats: FB_j FB_l FB_v HP_f HP_l HP_fl JFMT OL_m +(jobc,cpu,sl,re,cpu,prmgrp,m_swap,m_share,vm_lib,m_dt) +Note that "cpu" has two meanings. + +Add Beowulf support. This is ugly, since the current patches use a +daemon to collect info and add a HOST field after the PID field. + +Query optimizer, put cheap/required process selection first. + +Avoid reading both /proc/*/status and /proc/*/stat. + +Support printing the client hostname (the FROM that w(1) uses) in place +of a pty. + +Disambiguate narrow tty info.

Make sure that memory amounts are in +pages when they should be and in kB when they should be, not backwards. + +output encoding: UTF8 --nul --null + +Make BSD formats use non-standard BSD time format, at least when it +doesn't violate the "no whitespace" rule. + +Better unmangling of '?' as a tty.
