Just one question. What are you doing between the time you deleted the address
and data space and leaded the new one? Running out of /dev/null?

Yes, fork isn't a machine primitive. Very few UNIX system calls are. Read, for
example, "should" be:

	Read required block from file.
	Copy data from block to buffer.
	If any more blocks need to be read, repeat.
	Update current pointer.

A number of operating systems expect you to do all this stuff. I'll stick with
UNIX and read/write/fork/exec, thanks.
