	That makes things interesting.

	How does find out the address of original function?

	Does it copy old stub somewhere and return address to that?

	Or does it simply use stub as normal library stub (jmp xxx),
	and return xxx.  In this case it isn't surprising that
	it doesn't work with DOS-library.

	Exec manual don't say anything about return value,
	so does it just happen
	under certain circumstances or is it on purpose?
