No socket returned from bgsend()

If an expected failure mode, might be good to trap this and provide guidance to the end user.

No socket returned from bgsend() at /usr/share/perl5/Net/DNS/Async.pm line 112, line 188.

I think this happens when too many sockets are active at once - code should be modified to detect that and just sleep for a second or something.
