-/**
- * The worker struct contains per-worker information that needs to be
- * visible to the compiler, or rooted here.
- *
- * For 32-bit Windows we need to be aligning the structures on 4-byte
- * boundaries to match where ICL is allocating the birthrank and rank
- * in the __cilkrts_stack_frame.  It's 4-byte aligned instead of 8-byte
- * aligned.  This is OK because the compiler is dealing with the 64-bit
- * quantities as two 32-bit values.  So change the packing to be on
- * 4-byte boundaries.
- *
- * The fields of the worker struct can be classified as either local
- * or shared.
- *
- *  Local: This field is only accessed by the thread bound to this
- *    worker struct.  Local fields can be freely accessed without
- *    acquiring locks.
- *  
- *  Shared: This field may be accessed by multiple worker threads.
- *    Accesses to shared fields usually requires locks, except in
- *    special situations where one can prove that locks are
- *    unnecessary.
- *
- * The fields of the worker struct can also be classified as
- * "read-only" if the field does not change after it is initialized.
- * Otherwise, the field is "read/write".  Read-only fields do not
- * require locks to access (ignoring the synchronization that might be
- * needed for initialization if this can occur in parallel).
- *
- * Finally, we explicitly classify some fields as "synchronization"
- * fields if they are used as part of a synchronization protocol in
- * the runtime.  These variables are generally shared and read/write.
- * Mostly, this category includes lock variables and other variables
- * that are involved in synchronization protocols (i.e., the THE
- * protocol).
