1) Do not hide pointers to the collector, i.e. the collector will NOT 
search the window extra bytes (for instance) for pointers, or the hard
disk. If you need to XOR pointers to hide them do not use the collector
either.

2) In modern machines a collector slows down the program for at most
a milisecond in normal situations, that could be bigger but not much
bigger since the collector tries to spread out the GC time in each
allocation.

That's all.
