Tasks can not do file i/o, or anything else AmigaDosish. Processes can.
However, spawning a process does _not_ imply doing a LoadSeg. You can spawn a
process and give it the code in one of your subroutines in your already loaded
program to execute. You do have to deal with a few uglies like making it long
word aligned for the usual BCPL reasons, but it is possible.
