> thanks, it will be useful. That's pleasant to hear, Bulat. =) > whether it works in IO or STM monad? I made both versions. PriorityChansConvergerSTM is made in STM in one module. And in another module STM version is wrapped into IO. The IO version is a buildup on top of STM version, and it has additional properties: (1) It (PCC in IO monad) uses MVar locks to secure system from "waste work". I thought, that transactions don't look too lightweight, so few bottleneck would be great... The negative side of this, is that asynchronous exception may cause loss of locks. Probably in a future version I will try to introduce more advanced locking mechanics, which will be secure facing async-excpts... (2) STM version has interruptableRead and interruptableWrite operations, whose interruption is controlled with parameter (STM Bool). IO version also has these operations + interruptables, that are controlled by parameter (Chan a, a -> Bool). I'm no sure if interruptables for IO monad are made optimal - they do spawn additional temporary threads, but I didn't see any better way to make this interruption.
