rsync as last I looked at the source needs one of:

A. A working fork for straight port.

B. A C Compiler that support a thread local storage qualifier, which 
would allow a pass with an editor to do most of the work to convert it 
to threads.

C. A major bit of work to identify which static variables are used for 
sending, and which for receiving and then put them in a thread context 
variable.


I got pretty far with step C before I needed to move on to other things.

I have a proof of concept port which in spite of both threads sharing 
static variables with out coordination actually works about 95% of the time.
