Disable plalloc's free mem list by default in release build to prevent
performance impact.
DETAILS:
On a customer test file, SP03P_AC.prn, PL_KEEP_GLOBAL_FREE_LIST true
causes the page to take 400 seconds at 1200 dpi vs. 29 seconds with
this set 'false'. This _may_ indicate a memory leak, but a DEBUG
build is needed to investigate it anyway.
