Yes. We used to use APCs, but touching anything remotely related to
Winsock from an APC is not supported... We had a lot of trouble with it
initially, and it took a long support case with Microsoft PSS to figure
out what was broken, because this being unsupported was not properly
documented.

It certainly is ;-) We could probably find something more efficient,
but APCs are not the one.
