Bug ID: 48542
           Summary: Mono (and probably .NET) needs CreateThreadpoolIo
           Product: Wine
           Version: 5.0
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernelbase
          Assignee: [e-mail]

      Distribution: ---

Found testing LiveSplit 1.7.7 on Wine Mono from the master branch.

Mono's implementation of System.Threading.ThreadPoolBoundHandle depends on
CreateThreadpoolIo. Wine's stub of this function returns 0 and doesn't set last
error, resulting in the confusing message "System.IO.IOException: Success".

This can be more easily reproduced by running 'make test' in Wine Mono and
running tests/run-tests.exe
