I have not looked at this in a few years, but the issues is more that 
rsync initializes some data structures and then forks off processes.

But it is doable.  I make an experimental proof of concept port where I 
converted it to use posix threads instead of forked processes.

With the code base that I worked on, the main thing was identifying 
which of the common or static variables are modified by more than one 
thread.

The experimental version was working well enough that I could keep a 
local copy of the rsync source code in sync on my system with it.

I had set up a system to use editor macros to re-apply my changes to the 
lastest source, but had to move on to other things before I completed 
the port.

I currently use the experimental port binary several times a week for 
keeping my system up to date with blead-perl source.

Good Luck,
-John
