Implemented two new functions in sys: getcounts() returns a list of counts of allocations and deallocations for all different object types. getobjects(n [, type ]) returns a list of recently allocated and not-yet-freed objects of the given type (all objects if no type given). Only the n most recent (all if n==0) objects are returned. getcounts is only available if compiled with -DCOUNT_ALLOCS, getobjects is only available if compiled with -DTRACE_REFS. Note that everything must be compiled with these options!
