If you look at the use cases, it's mostly I/O. There are no sane ways to 
interrupt I/O.

With network I/O, poll() cannot easily be interrupted by an in-process event.

With local disk I/O, it's even worse. poll() returns immediately regardless of 
data being available or not. The only way to pace is to run in a separate 
process and lower the I/O priority of that process.
