Hi Rob,

Your change looks good. I think on AIX we still use the
PollSelectorProvider but your change doesn't change that. I've did a quick
build and ran the corresponding JTreg test on AIX without a problem.

We may tough consider a better implementation on AIX by using the pollset
API [1,2] which is similar to Linux epoll. I therefore also forward this
message to the ppc-aix-port-dev mailing list in the hope that some IBM
colleagues may volunteer :)

Regards,
Volker
