When creating new threads, initially block all signals.  It's up to the
client code (in vg_libpthread.c) to set the appropriate signal mask when
its ready.  This prevents a bug where a thread gets sent a signal before
even running any of its initialization code, which can cause problems
(particularly if the signal handler directly or indirectly uses TLS).
