timeouts in Handle

[gleeco]

i'm looking to limit my handles on a socket for reads and writes.
Assume i have a long-running socket conn that i'd like to keep open,
but want to put each request under a timeout limit. In the docs, i see
wtimeout and rtimeout and am wondering:

* OK to fire off another write (eg. request to remote) after the
timeout cb occurs?

* what happens to the data that the remote socket sends after the
rtimeout?  Does the AE kernel discard this?

* are there some examples / modules where clients put the handle on time limits?

--thanks in advance,
