An opposite timeout approach could be:
1) set a flag
2) create a trap handler that clears the flag
3) do your write in backgrounded subshell, that signals the parent when
finished
4) after spawning the subshell, sleep (your timeout)
5) then check the flag
I think I'll try this out. How do I send a signal to the parent from the
subshell? kill? Do I need to pass the parent pid to the subshell somehow?
