None that I know of. The documentation doesn't list any. And remember
that such basic functinos as WriteFileEx and friends use APCs - and
there is no mention of sockets being affected by that.
I've used them in sockets based applications several times without any
issues, but it might be that this is a border case somewhere.

Haven't looked at the details of this problem yet - can you elaborate a
bit on what you're seeing?
(And what did you have to fix?)
