Can you just use a bottom half to defer this work to the I/O thread?
Bottom half scheduling has to be signal safe which means it will also be
thread safe.

Not that straight forward as I would have to pass arguments to the
bottom half.

Can you add a variant of qemu_bh_new that accepts a sizeof for the new bottom half? Then the bottom half itself can be passed as the opaque and used for the arguments.
