Suppose the following happens: (1) Thread A calls readChan on an empty channel and waits (2) Thread B puts something to the read-end of the channel using unGetChan When a GHC program does this, both threads are blocked! Is it the behaviour we really want for unGetChan, or should we fix the implementation for Control.Concurrent.Chan? Thanks, Peng
