MainLoop was meant to be a general event multiplexer. One of those
events can certainly be "a certain amount of time expiring".
So, you could write something like:
loop.RegisterAlarm(seconds(N), [&] { loop.RequestTermination() });
which would translate to an appropriate timeout argument to ppoll.
I think in the common case of listening for a remote connection infinite (or
very very long) timeout with signal interrupt is the preferred approach. There
are other situations where we use SelectHelper with smaller timeouts, and I
think ultimately we should replace SelectHelper with MainLoop be
(1) is okay, except pretty much every time so far I've ever said "operation X
can't possibly take more than N seconds" somebody finds a case in which that
assumption was wrong. So you end up having to make the timeouts so long they
look like stalls anyway... An explicit cancellation gesture is
Ultimately I think the solution here is two changes
(1) We should add a timeout to MainLoop so that it doesn't wait forever unless
we really want to wait forever.
(2) MainLoop can exit on sigint for any platform that has ppoll, pselect, or
kevent, so we should probably set that up too.

Seems to me a better UI would be to make ^C interrupt this wait. That seems to
me better than putting in some arbitrary timeout.

Hi Chris, Pavel,
I've got a problem launching the hexagon simulator from lldb. It's launched
the same way that debugserver/lldb-server is launched, with reverse connect
on a TCP socket. The user can modify the simulator command line (using
target.run-args), and can easily give a set of options tha
