All the erl_driver functions are documented as "thread-safe",
sometimes with the caveat "when the emulator with SMP support is
used." Unless it's stated in the docs, it's probably not safe to call
them from an async thread without explicit synchronisation. I'm sure
one of the OTP team will dive in and say if that assumption is wrong.
