:What happens if a second signal gets delivered to the process before
:the first signal is checked by the userland process?
:

    Not sure what you mean.  A second mailboxed signal or a normal signal?
    Using the signal number or a different signal number?

    I do see one case that I probably need to address, and that is if a normal
    signal gets delivered to a process after a mailbox signal has been 
    delivered, but before the process enters a system call.  The second
    signal vector could cause the mailbox process flag that causes the
    system call to return EINTR to get cleared.  I probably need to save
    the process mailbox flag and OR it back in when the normal signal returns
    from its handler.  Not a big deal.
