I think it is the seek that is generating the processes.

No. perl's seek doesn't imply spawning a new process. It boils down to a system call done in the same process, on my system (Linux) it is lseek(2).
Does perl sport an echo function (see perlfunc)? There.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'

In reply to Re^3: What is this process by shmem
