            Bug ID: 51319
           Summary: server: spins in a loop consuming 100% of a hardware
                    thread until closed, makes wineserver SCHED_FIFO
                    unsafe.
           Product: Wine
           Version: 6.9
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wineserver
          Assignee: wine-bugs at winehq.org
          Reporter: spambox1 at koolhoven-home.net
      Distribution: ---

wineserver can be induced into an infinite loop of some sort and take up 100%
thread/hardware CPU time. This makes setting SCHED_FIFO and SCHED_RR on
wineserver unsafe, will cause immediate system lock if attempted.
