[Bug 36040] Environment variable to disable wineserver persistence

http://bugs.winehq.org/show_bug.cgi?id=36040

--- Comment #4 from Josh Triplett  ---
This is a dejagnu-based testsuite compiling and running test applications,
cross-compiled via mingw, and run via wine and binfmt-misc.  (Thus, I don't
have much control over the invocation of each test, and I'd like to avoid
adding any wine-specific code around test invocation.)  Each test blocks for a
while before completing.  I can watch "ps" when that happens, and observe that
wineserver is the only process running; the moment wineserver exits, the
testsuite moves on to the next test.
