[erlang-bugs] efile_drv & async thread key

[Rick Reed]

It looks to me as though there's a bit of a problem in the way efile_drv.c
generates the
key that's used to select an async driver queue.  It uses the address of
the port which
on our system is 8-byte aligned.  Meanwhile, erl_async.c does a simple mod
operation
with the number of async threads, so the number of threads that can
actually be used
by file operations is 1/8th of the number configured.  I suspect this isn't
intended.
