Reused means that, if kmail requires an imap4 connection and kio_imap4 is 
already there, it'll reuse that kioslave instead of spawning a new one. If 
the connection is already open, that's something else. But I don't believe 
one program is allowed to hijack the open connection of another.

That currently happens, but I think the kioslave forking from the master app 
should prevent that.

Agreed.

That's possible. It would require that a stub executable be created for 
every kdeinit .so module. It isn't hard, actually -- it would be basically 
the same code, with the difference that the generated binary would be 
linked to a different .so.

Thus, we end up with:

	lib/kde3/kio_imap4.so
	bin/kio_imap4 (or maybe not in bin/ so as not to pollute it)

The latter would dlopen the former on invocation.

libkio would have to be modified to use something like KDE_EXEC_SLAVES in 
addition to KDE_FORK_SLAVES.
