I'm finding ppoll() unexpectedly stuck when waiting for POLLIN on a
local TCP socket.  The isolated code below can reproduces the issue
after many minutes (<1 hour).  It might be easier to reproduce on
a busy system while disk I/O is happening.

Ugh, I can't seem to reproduce this anymore...  Will try something
else tomorrow.
