That is entirely possible but unlikely.  The present flakey behavior is not
surrounding AcceptEx(), it works for the vast majority of configurations
until incomplete socket providers are added.  But I'd be happy to see a patch
to resolve AcceptEx dynamically.

The issues now are twofold;

 1. When using AcceptEx() we always attempt to recycle the socket context.
    We should make this configurable and avoidable.  Many socket providers
    have implemented AcceptEx() and then trash the socket making it fail
    any attempt at reuse.

 2. When using accept() we are doing 'something wrong' compared to our 2.2
    code, which causes the timeouts to be other than expected by APR.  This
    in turn causes the mod_ssl blocking read to fail to block.
