Re -the subject- : I looked at the evaluator code from a threading perspective a few months back, and come to the conclusion that it is totally broken. The memoization code rewrites expressions without locking or atomicity, and if you have two threads memoizing (ie. executing the same code for the 1st time), you will have unpredictable effects. -- Han-Wen Nienhuys - [EMAIL PROTECTED] - http://www.xs4all.nl/~hanwen
