Two changes:
...
1. Delete type handle regardless of whether a collision occured
2. Remove a MAJOR pessimization of runtime performance (thought be be an optimization at the time).
This second one was causing a 105k llvm file (from gcc) to parse in 58 seconds... without the
'optimization' it now parses in 3.64 seconds. I suck.
