Message1632

I was able to reproduce the effects with the attached test program.
Platforms: Ubuntu 6.10, Windows XP
Processors: single core, single core HT (hyper threading), dual core
JDK's: JDK1.4.2_14, JDK1.5.0_11

The test program takes two options:
 - number of threads to start
 - number of seconds to pause before starting the threads (useful for remote debugging)

ImportErrors or NameErrors occur between 5 and 50 threads on almost every platform / JDK combination.
(I was not able to reproduce them with JDK1.6.0_01 on my single core laptop).

Luckily problems do not go away if a debugger is attached and paused at ImportErrors.
