This causes problems in code of the form
if (/* condition */)
FD_ZERO(&thing);
else
do_other_thing();
Wrapping the call to memset() in a do/while block fixes the issue.
For some reason X/OPEN requires that fd_set has a field fds_bits. Xproto
requires either fds_bits or _fds_bits to be present, so the field 'bits'
was renamed 'fds_bits'

64 was cutting it pretty close, especially now as we start using file
descriptor passing more and more.
This (1024) matches many other systems, and if we need more there's
always sys$poll().
