The
opening of the communication named pipes and thereadoperations are blocking. This introduces a timeout.High level:
we associate a thread with
open, which waits for a signal(Event), with a timeout. If it times out, the thread opens
the associated pipe, which unblocks the main
openwrites aren't expected to block
reads are. To address, we poll (
select.select) before reading,with a timeout.
The design treats the timeout as resetting for each blocking op.
This is just to simplify the design - rather than checking passed
time.
