Multithreaded programs don't work (reliably) in x86 user emulation mode. This is a known (longstanding) bug. ARM hosts are also currently known to have problems (as stated in the qemu 1.0 release notes).

Running the same version of wine through qemu-user-i386 running on an i386 host works fine with both wineserver and wine being emulated; that's the result I'm trying to achieve.
