Thanks again for your time
Yes my desktop also has 0 for overcommit_memory.
I do not have root permissions on the Centos and none of the future users will have it either.
I will need to run on even larger datasets of human patients, so can't waste any additional memory

I will have look at POSIX::RT::Spawn

It is weird that there is no easy solution for this, is this also with python or other languages?
Because the mother process doesn't need to interact with sister process. I can write the information I need for 'blastn' to a file, then generate a new file that the mother process opens to read the result.<
So only the timing when the sister process starts is important, there is no need for a direct interaction.
