- This is not a bug. All operating system kernels have resource limits. Congrats,
- You've discovered one of mach's. There's more than one way to kill a kernel by
- exceeding its limits, many I'm sure will remember that oldie but goodie
- "while(1) fork() ;". You have to program around these limits, you can't just
- claim its a bug and push it onto someone elses plate. I don't remember
- which header file contains a macro indicating the max number of threads per
- task, but I do know it exists ( anyone care to jump in with that info? ).

- And files that will hang the system if 17 characters are inserted!! ( See
- above ) Is it to late to have NeXT wipe the Examples directory clean in
- 3.0!!! And we must get rid of that nasty compiler, it could be twisted
- into a tool of system destruction! :-) :-) :-)
