is there any way of running a huge number of processes without
hitting the dreaded fork problem? i would like to run say
1k processes (quite small) but since (most?) implementations
use fork to create a new process very soon i run out. 

I am currently using mpich on a four hpux workstations. In a few
weeks i will be switching to a nice new Origin (will that
make any difference?). Perhaps other implementations use somethnig
more lighweight?
