Cygwin handle leak in net.cc

I believe there's a handle leak occurring in
The functions recv/recfrom and send/sendto use
the wsock_event class that obtains a handle using
wsock_event::prepare allocates the handle.
When this class is used, if wsock_event::wait isn't
invoked, the handle won't be freed.
I observed this in the recv function.
In Windows NT's Task Manager, I was watching
fetchmail's handle count, and it quickly grew to 60,000.
I modified the fetchmail source to obtain its handle
count using NtQueryInformationProcess from NTDLL.DLL,
and recv() was the culprit.
If the wsock_event class was modified with a destructor
that did this:
I think this would fix the problem.
This would ensure the handle is freedl when
the object goes out of scope.
