I can confirm that building QEMU 2.5.0 from source, all the multi-thread issues seem to be fixed.

Specifically, the mentioned dotprod_mutex.c example, even when modified to use 100 threads, is always running in the qemu-arm User mode emulator.

Tested in Ubuntu 14.04 x86_64, with all the updates installed.

Note that instead the QEMU 2.0.0 from the Ubuntu 14.04 repository is having issues even when using workarounds like running it with "taskset 0x1" to force the execution to a single CPU.
