 	sys/kern/sys_select.c: revision 1.42-1.45
 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.
