I can confirm that select on win32 only seems to consider the first 64 file descriptors. Per
haps somebody from Activestate could check that the change to allow 2000 file descriptors re
ported for build 1001 works , and has not been regressed..

I have just tried your code on Linux, and it seems to work as expected, i.e. pings seen on t
he server immediately after they are sent. So you may want to consider switching OS.
