The implementation of os.spawnv when called with the
P_WAIT flag calls waitpid to wait for the subprocess.
If this function is aborted early because of a signal,
i.e. if it raises OSError with EINTR, it should be
called again.

I ran across this bug when trying to write a test case
for a script that stops another process. Both the
script and the other process are executed as
subprocesses of the test program. The stop script is
executed with os.spawnv(P_WAIT,  ...) to wait until the
script completed. Unfortunately when it stops the other
process a SIGCHLD is sent to the test program which
then aborts the waitpid with an exception.
