I think this dates back to when C-g and/or other handlers called
longjmp. Since getpwname etc. are not async-signal-safe we needed to
block input around them, so that C-g's effects were deferred until these
functions returned. If I'm right, we don't need to block input around
them any more, since our signal handlers are safer now.
Similarly for MALLOC_BLOCK_INPUT; we should be able to get rid of its
machinery now.
