No, it crashes (actually, locks up) under load because of deadlocks. Not
good for an unattended machine.

2.1.x gives much bettter performance under SMP than the 2.0 kernels
because of the granularity of the locks. 2.0.x is bad because it breaks.
Linus gave up looking for the cause and rewrote the SMP stuff completely
for 2.1.x
That information came from the mouth of a local kernel hacker named
Torvalds who works over at Transmeta.
