--- Comment #2 from digitman digitman63@gmail.com --- 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
