Comment 1 Arjan van de Ven 2001-08-16 13:01:17 EDT
The default max threads value depends on the amount of memory actually.
The kernel uses the formula:

max_threads = mempages / (THREAD_SIZE/PAGE_SIZE) / 16;

which _should_ provide a reasonable default for your system.
Documenting this default change might be the best thing to do.
