Capture calls to execve() to make sure that the
signal mask is set correctly on the thread that is going to
continue in the new process. Required for Posix compliance.
This is not perfect and better fixes may happen after 5.3
is released.

Allocate red zone and stack space together and then split red zone from
allocated space, orignal code left red zone unallocated, but those space
can be allocated by user code, and result was providing no protection.

a knob to force process scope threads. If the environment variable
LIBPTHREAD_PROCESS_SCOPE is set, force all threads to be process
scope threads regardless of how the application creates them. If
LIBPTHREAD_SYSTEM_SCOPE is set (forcing system scope threads), it
overrides LIBPTHREAD_PROCESS_SCOPE.
$ # To force system scope threads
$ LIBPTHREAD_SYSTEM_SCOPE=anything threaded_app

Check debugger suspending flag for system scope thread.2004-08-08T22:42:11ZDavid Xudavidxu@FreeBSD.org2004-08-08T22:42:11Zurn:sha1:78f687539abca73a1b8d0a53086b991df21f8b78

LIBPTHREAD_SYSTEM_SCOPE in the environment.
You can still force libpthread to be built in strictly 1:1 by
adding -DSYSTEM_SCOPE_ONLY to CFLAGS. This is kept for archs
that don't yet support M:N mode.
