Added files:
lib/libpthread/thread thr_execve.c
Log:
Add a wrapper for execve(). The exec'd process must be started with
the signal mask and pending signals of the calling thread. These
are stored in userland in libpthread.
There is a small race condition in this patch which could cause
problems if a signal arrives after setting the (kernel) signal
mask and before exec'ing. The thread's set of pending signals
also are not yet installed in the exec'd process. Both of these
will be corrected with the addition of a special syscall.
