The C accelerator for the collections.Counter class (_count_elements() in
_collections.c) is slower than the pure Python versions for data that has many
unique entries. This is because the fast path for dicts is not taken (Counter

Tim Golden added the comment:
The Ctrl-C handling in Python on Windows is a bit strange in places. I'll add
this to my list of things to look at. If you'd care to walk through the code to
produce a patch or at least to point to suspect code, that would make it more
likely that it be fixed.
