We are already in the QA phase for the 6.0s2 release, so for
6.0s2 it's not an option. I try to test poll() implementation for
the next release. We also have to be sure that any dependence from
FD_SETSIZE is checked/reviewed in the entire source code.

It's also a problem to test the fix, because I don't have access
to clusters with more than 1024 hosts.

Best regards,
