Keep initrd tasks running?

I am confused.  I thought that once the initramfs init execs the real 
init, the initramfs is freed.  It can't be freed if there are processes 
that still have open files there, so that would seem to prevent any 
processes being started in the initramfs and continuing after the real 
system is booted.
