to interrupt on i/o operations you send a note to the process.
for ioproc(2), here is iointerrupt() that does that. for timeouts here is
a alarm() function (see sleep(2)) that will fire a note on you when the alarm
expires.
notes should also work for rendezvous()/alt(), but a better way is to include
a timeout/cancel channel in your alt() operation. as a example see
/sys/src/cmd/rio/time.c. here we have a central timer process
that does a sleep and sends a message to channels associated
with timers when they expire.

Thank you very much.
Where can I find the explanation of the interrupted system calls behaviour ?
In Unix I sometimes found quite difficult to deal with them.
What about Plan9 ?
