My question is if there is an effecient way to block / wait on multiple
MVars. takeMVar & readMVar can wait on one MVar. The puspose is to be
able get the reults of a list of AIO operations, in the order in which
You could iterate through the list and tryTakeMVar, or spawn a thread to
block on each one and then write into a central MVar or Channel. The
latter is the approach that I am currently using.
the reason you can't simply set them up to all write to a single MVar in
the first place is that it is desirable to be able to have the same AIO
operation be synchronised by multiple readers / clients.
Is there a better way to do this? Or would it need a new MVar /
