  Yes.

  We don't need that limit.  The server should not be running more Perl
threads than system threads.  It also should not be running less Perl
threads than system threads.

  It should be running one Perl thread per system thread.  The server
core already manages min/max spare threads, idle threads, etc.

  The pthread keys in the current rlm_perl should be moved to the
"perl_inst" struct.  The keys should be allocated per thread, and not
via pthread_once.
