PR/54158: Anthony Mallet: poll(2) does not allow polling all possible fds
(hardcoded limit to 1000 + #<open-fds>). Changed to limit by the max of
the resource limit of open descriptors and the above.

Remove the slop code. Suggested by mrg@

Use the max limit (aka maxfiles or the moral equivalent of OPEN_MAX) which
makes poll(2) align with the Posix documentation (which allows EINVAL if
nfds > OPEN_MAX). From: Anthony Mallet

Add slop of 1000 and explain why.
