- You want to know about running out of VM? The program I am writing for my
- project uses Dijkstra's algorithm for searching a graph. Running on a 40Mb
- Sparcstation with 120Mb of swap space, I got out of memory errors. OUCH!
- (I soon removed the bug that caused the problem - *severe* memory leakage!)
