test-hmp fails for me on OSX hosts:

TEST: tests/test-hmp... (pid=6008)
  /aarch64/hmp/n810:
qemu: qemu_mutex_lock: Invalid argument
Broken pipe

GTester: last random seed: R02Sd714920da46f8a0e37afec762c6ee23b

etc etc.

Can't do a backtrace, I'm afraid -- Apple's debugger doesn't seem
to work if you're not root and the lack of X11 forwarding on the
box I'm using remotely interacts really badly with qtest's
desire to run qemu as a background process that it's hard to
attach a debugger to. Something's probably not initializing
a mutex, though -- Linux by default treats zeroes as a valid
initialized mutex so it won't notice. You may be able to repro
on Linux by using the Linux PTHREAD_MUTEX_ERRORCHECK_NP
mutex attr, possibly.
