           Summary: ActiveX Control Pad installer hangs sometimes on exit;

A user said that ConvWPT ran in Wine, but gave a very complicated recipe,
so I tried simplifying it.  Along the way, I noticed that Microsoft's
ActiveX Control Pad installer hangs sometimes on exit.  Here's how to
reproduce:

1) Do "winetricks wsh56", else "winetricks fm20" will fail with dialog
"Setup has determined that Microsoft Internet Explorer 3.0 was not detected."

2) Do "winetricks fm20".  This will complain "Setup was unable to start DDE
communication with the desktop".  Click Ignore.
(This is probably bug 9159.)

When the installer is done, it sometimes hangs with

err:ntdll:RtlpWaitForCriticalSection section 0x7ef2b3c0 "syslevel.c:
Win16Mutex" wait timed out in thread 002f, blocked by 002e, retrying (60 sec)
err:ntdll:RtlpWaitForCriticalSection section 0x7efec5e4 "loader.c:
loader_section" wait timed out in thread 002e, blocked by 002f, retrying (60
sec)

Using winedbg, I was able to get a backtrace of those threads by pressing ^C
and then using the bt command:
