Wait what: `parallel` is a Perl script!? [1]

I would have thought it's black magic with assembler optimisations for MIPS and special considerations for HP-UX...

assembly optimizations for starting processes?

Maybe for reading the input, splitting it, and assembling the possibly-very-long argument lists passed to the processes.

Command lines can be very long, so you can potentially read a million lines between executing processes.
