The bottom line is multi-threaded programming is HARD, not just a little tricky as you seem to be thinking, but VERY VERY HARD. Add to this the fact that, despite me telling the author several times, the lock thread function does nothing and you have serious issues.

It is possible to write PAWN-based critical section locks using, for example:

http://en.wikipedia.org/wiki/Dekker%27s_algorithm

or:

http://en.wikipedia.org/wiki/Peterson%27s_algorithm

However these only work for two threads, not many, and as most PAWN natives are not thread safe you may need to put critical sections around almost everything, making threads actually WORSE than no threads.
So even it could be possible to do multithread in PAWN, but we'll need to lock the threads to prevent using the functions at the same time. However this will cause waiting issues, which do no (or very few) performance increase.
