prims.cc (_Jv_CreateJavaVM): Add comment about initialization order.

* prims.cc (_Jv_CreateJavaVM): Add comment about initialization order.
* posix-threads.cc (_Jv_InitThreads): Call block_sigchld() here to
ensure that GC threads inherit the new signal mask.
(block_sigchld): Call JvFail rather than throwing exception if
pthread_sigmask() fails.
