yeah, this is what i am currently doing. for the non-hardcore non-cmdline
sysadmins ;-) it might be a useful addition though.

on my systems the threads have each like 10-20M RSS, SIZE is
~15-35M. memory is not the issue i think, also if the Linux threads
disguise themselves as processes (different PIDs) which initially
confused people here, other UNIXes are better with respect to
that. but what i do see is a performance impact, the simulations take
longer on systems where the web service is running. according to the
intial testing looks like if i run two big jobs (~1.5-2GB) on the 4GB
systems makes the omaws32 threads to use more CPU time. a guess would
be that it is has something to do with the kernel or with the
software. if i find more out i post it to the list.
