I finally got back to this, and checked in some cleanup for both the pipe()
calls and the read()/write() calls that were causing compiler warnings.
 This gets rid of all the "ignoring return value" compiler warnings, and
should make some of the read/write calls slightly safer (since they now
handle EINTR).  There is one remaining FIXME (in exec.c) where I didn't
error-handle an mpipe() call.  Since it wasn't error-handled before, it will
be fine for now, but we may want to figure out how to do an error exit from
that point.
