[Haskell-cafe] Chan with priorities

[Bulat Ziganshin]

Hello Haskell-cafe,

can  you please point me to any OSS implementation of IO Channels with
priorities  -  i.e. data pushed to the Chan using high priority should
be read prior to the data pushed with lower priority:

pushChan ch 1 'x'
pushChan ch 2 'y'
readChan ch >>= print -- prints 'y'

i've  found only STM implementations - i don't know STM enough, may be
i just need to convert STM to IO operations?

i  don't  expect  strong  guarantees, my algorithm will remain correct
anyway. and i don't have lot of objects, it's just a few dozens
