There was a theoretic race in this example: If the server was very fast at handling commands then it's possible that in a call such as: cookie = nbd_aio_pread_callback (..., callback, ...); buffers[i].cookie = cookie; nbd_aio_pread_callback finished and calls the callback before returning. buffers[i].cookie would therefore not be set, but the callback() function was checking the list of

Previously discussed here: https://www.redhat.com/archives/libguestfs/2019-July/msg00213.html It turns out that deferring callbacks is a PITA. (It would be a bit easier if C has closures.) However by rewriting the example we can avoid the need to use the cookie at all and make it run a bit more efficiently, so let's do that instead. Rich.
