The 1024 process limit in linux is a old limit (probably in kernel version
2.0 or 2.2). Even then it could be increased by changing a #define, IIRC.
With the current libpthread/kernel the limit is more like 8196 threads
per process and with linux 2.6 and glibc 2.3 there won't be any hard
limit.
So, we need to not limit artificially the number of threads allowed
(and we need to check a C# program gets the proper notification when
thread creation fails).
