2.4 allows you to set the maximum number of threads/processes via the /proc
file /proc/sys/kernel/threads-max. From poking around in the kernel source,
the default limit is such that the maximum amount of memory consumed by all
of the in-kernel thread structures would be half of physical memory (not
virtual). As an example, on my 192M x86 machine that translates into a
default maximum of 12288 threads (12288 * 8K/thread = 96M).
