[Bug 28042] New: [regression] deadlock introduced/exposed with recent changes to winmm

http://bugs.winehq.org/show_bug.cgi?id=28042

Summary: [regression] deadlock introduced/exposed with recent
                    changes to winmm
           Product: Wine
           Version: 1.3.26
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Running recent versions of Wine (1.3.25 or 1.3.26) causes "Cuban Missile
Crisis: The Aftermath" (known also as "The Day After: Fight for Promised Land")
to hang during startup with a message similar to:

err:ntdll:RtlpWaitForCriticalSection section 0x7efec8e4 "loader.c:
loader_section" wait timed out in thread 001f, blocked by 0009, retrying (60
sec)

I cannot test this as currently I'm not in possesion of suitable software but
there is a possibility that other games using the Enigma engine might suffer in
the same way: Blitzkrieg, Blitzkrieg 2, Stalingrad. This needs confirmation
though.

git bisect converges on the following commit:

Switching between hardware or emulation in sound settings does not help,
neither does turning off sound entirely.

I will gladly provide any additional logs or information on request.
