Hi Armin,


This is a known problem with the cygwin layer, currently efforts are
underway to exactly define where the problem resides, however it seems
when "processes" are threaded and sockets are used in the process, in some
instances when the socket is closed the cygwin layer doesn't pass the close
onto the winsock, hence the socket as a descriptor (win32 handle) remains.
This causes the following:

1. Win32 Handles not being freed up
2. Virtual and Swap memory not being freed up

You may want to try installing the latest cygwin1.dll as of 10th Nov
from the snapshots section. Some aspects of the problem have been resolved,
this may remedy your current problem.
