All the global state (GS) API functions will check that
qemu_in_main_thread() returns true. If not, it means
that the safety of BQL cannot be guaranteed, and
they need to be moved to I/O.
I'm getting this crash:
$ qemu-system-i386
Assertion failed: (qemu_in_main_thread()), function blk_all_next, file
block-backend.c, line 552.
Abort trap: 6

qemu-system-i386 was compiled with optimization - stepping may behave
oddly; variables may not be available.

Forgot to paste the backtrace:

I think Paolo and Peter talked about this a couple of days ago on #qemu,
and have already found a solution if I remember correctly.
Maybe it's worth to check with them first.
Maybe this discussion?
