commit 11c6c5099fb750e90f7ecdeb901897f3b184a714
Author: Josh Stone <jistone@redhat.com>

    Make sure that sigaction always starts zeroed
    
    On some systems, stapsh's child process was getting automatically
    reaped, which caused an error when we tried to waitpid().  This was
    because we weren't fully zeroing the sigaction, so sa_flags was
    uninitialized (and happened to contain SA_NOCLDWAIT).
    
    This patch sprinkles memset-0 on sigactions throughout.
