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). git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2332 a5019735-40e9-0310-863c-91ae7b9d1cf9
