          Issue ID: 14584
           Summary: spurious autotester deadlocks
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: druntime
          Assignee: nobody at puremagic.com
          Reporter: code at dawg.eu

Happens in multithreading unittests such as core.sync.rwmutex or
core.sync.semaphore.

I just encountered a process that dead-locks in the the newly added
synchronized statement of the rt.trace tls dtor.
