Demonstration of leaks

WineStaging 10.4 (WINESYNC=1):

Creating and then destroying a thread causes file descriptors opened by the
WINESERVER process to leak

To reproduce the problem, run the FileDescriptorsLeakDemo.exe application from
the attachment by command

WINEESYNC=1 wineconsole FileDescriptorsLeakDemo.exe

During the execution of the application, periodically monitor the statistics of
open descriptors by running the wineserver_desc_stat.sh script from the
attachment

Does this happen without esync enabled?

--- Comment #2 from digitman  ---
There is no i_node(eventfd) leaks in WINESERVER with ESYNC=0

With ESYNC=1 the test application attached to the bug report hangs dead when
the number of i_node(eventfd) in WINESERVER reaches a value close to the
maximum possible.

If necessary I can provide the source code of my test application
