I found a good solution to this problem in Richard Steven's
_Network_Programming_. It seems like everything shows up in Steven's
books! Rather than pausing, you do a blocking read on a pipe. You
only write to the pipe from within the signal handler. However, this
brings up the better question:

How does that help? I interpret "use asynchronous calls" to mean "use
fcntl to set an FN_NOTIFY on the directory in order to be alerted when
something needs to be done." But the method of doing that which I
outlined above has a critical section in which the incoming signal will
not be noticed.

Use asynchronous calls and/or a separate thread.
