Re: threads and their alternatives

with huge learning curves, that produce complicated, hard to maintain code.
Can't agree with this statement, I had to work with some projects with POE and AnyEvent and it wasn't especially hard to learn and maintain. On the other hand I will not call threads simple, as most people (I'm judging by code I had to work with) either had no idea that they need to lock shared variable before accessing it at all, or are not able to implement it properly.
