Now pipes and file descriptors seem dangerous to me, since they are not necessarily threadsafe (especially with Cocoa)

Now, this is definitely not true. Two threads should be able to talk to each other on opposite ends of the same pipe without problem. And Cocoa doesn't have to enter the picture - you can use the raw system calls.

According to:

http://developer.apple.com/documentation/Cocoa/Conceptual/ Multithreading/Tasks/foundation.html

It says facilities which are generally thread-unsafe are:

... NSPipe ...

I am unsure if the underlying BSD pipe implementation is threadsafe, I can't see this one way or another by googling.
