I”Ēm out of the loop on this one.  I”Ēm assuming that this occurs when a
program creates a lot of symbols based on user input.  If that”Ēs the
attack vector, shouldn”Ēt that be fixed instead of letting the GC
collect Symbols, which, as has already been stated, seems very hard to
do correctly, if at all?
