Global perl variables across all threads with rlm_perl ?

OK, I figured out something that works :)

I have rebuilt rlm_perl without ithreads so that it is considered as "thread unsafe" by FreeRADIUS.
This allows me to have in the perl execution the same persistent variables for all FreeRADIUS threads.

I know I don't have parallelism anymore in the perl module, but it's ok for me. Most of this code would have been in critical section anyway.
I have ran some preliminary benchs which yield very good results. It's very fast, even with the lack of parallelism.

Thanks again for your time.
