Underhanded Code Contest

[iago]

I remember reading about this last year, and it was a pretty neat contest.  It's going on again this year.  Basically, you have to write some code that runs fast on one OS, and sloooooow on another.  But you have to make it look perfectly innocent so that somebody viewing the code doesn't immediately see what's going on.

Use JavaOp. It runs horrible on Windows (RAM/processor usage) but fine on Linux!

EDIT -
Oh, its C only. =(

The program is supposed to read a set of words on stdin, and print a frequency count of unique words in lexicographical order.

(Don't feel too bad, I missed it too).
