There are MT-Safe versions of them on IRIX, I think. Pthreads are certainly
not portable to all problems anyway :)

Yes, I agree that it is a not good idea to interleave async-IOs on the same
FD. More importantly, I do not think it is needed. However, I think that the
async-code should not mix sync-, async-IO, and even calls to select() as it
does now. This unhealthy mix creates a lot of problems, IMO.
