Yeah - the shim stuff is now all in the .XS file mentioned in the 
original mail. 

For what it's worth you can see the code I'm working on here 

https://github.com/simonwistow/Log-Syslog-Fast/tree/tls_support

(which, caveat, still needs checking over for correctness, 
non-leakyness and general stinky code)

The relevant bits can be seen in Fast.xs and the options(..) method, as 
used in new(..) but basically it's a XS method with variable args that 
loops through the remained of the stack, 2 at a time, and then added the 
variables to a struct and passes that struct into the C.
