hang in mci tests?

[Dan Kegel]

Hi Joerg,
I had a new hang on yesterday's git under valgrind:

../../../tools/runtest -q -P wine -M winmm.dll -T ../../.. -p
winmm_test.exe.so mci.c && touch mci.ok
preloader: Warning: failed to reserve range 00110000-68000000

I had to kill it; dunno if the leak was because I interrupted it or not.
