Hi,

>I/O in my backend.

the current OS/2 release is using threads instead of fork() calls;
that's because low-level scsi handlers can't be used with fork().

So I have implemented a sanei_thread lib that replaces the following
calls:

fork
kill
waitpid
wait

On non-OS/2 platforms, sanei_thread simply calls the same functions.
With sanei_thread only a few changes to current code are needed (mainly
thread start and parameter checking).

Maybe it is possible to expand such implementation.

Bye,

        Yuri Dario
