Well, I like 5.005 threads :)
Just to compare: My script that uses threads shows 3 versions of itsself in 'ps -el' all with a size of about 2400. According to 'top' however, each thread is using about twice that amount of memory (4600), and 1600 shared. So one of them must be wrong, but which?

C. *waves the threading flag* ;)
