mlm_selftest.exe -t mlm_server crashes on exit in Windows

[opedroso]

Got latest zeromq, built all in Windows using Dev2013.

When Malamute selftest runs, it crashes on exit, even thought actual test passed.

X:\3rdparty\malamute> builds\msvc\vs2013\DebugDEXE\mlm_selftest.exe -t mlm_server
Running malamute test 'mlm_server'...
 * mlm_server: I: 16-04-26 14:45:31 client address='(null)' - invalid command
OK
Assertion failed: Successful WSASTARTUP not yet performed (..\..\..\..\src\signaler.cpp:261)

It is interesting that it works for several of the executables built, but fails for these:

X:\3rdparty\malamute\builds\msvc\vs2013\DebugDEXE\mlm_selftest.exe
X:\3rdparty\malamute\builds\msvc\vs2013\ReleaseDEXE\mlm_selftest.exe
X:\3rdparty\malamute\builds\msvc\vs2013\x64\DebugDEXE\mlm_selftest.exe
X:\3rdparty\malamute\builds\msvc\vs2013\x64\ReleaseDEXE\mlm_selftest.exe

Commonality is these are all using LIBZMQ component as DLL.

Closing this issue, since this is a LIBZMQ problem:
zeromq/libzmq#1708

I did this and the problem went away.

x:\3rdparty\malamute>git diff --patch src/mlm_selftest.c
diff --git a/src/mlm_selftest.c b/src/mlm_selftest.c

I wonder if I should change the test or wait for the LIBZMQ issue to be fixed.

Put zsys_shutdown() at the end of the test solve the issue.
