Ignoring issues like potential non-reentrance of code and other library issues, C++ is perfectly capable of being used to make programs that use pthreads. It's not a bad time at all... Python apparently has threading and I've seen "from miltiprocessing import.." in Python before. Tcl also has threads, or you can just write things to be event driven. I have never used Tcl to implement a multiprocessor solution, but others have. Because sockets are a first-class object in Tcl, that approach is quite fruitful. I use something you could roughly call "coroutines over a network" daily in Tcl.
