It's my understanding that a re-compile is triggered by a mismatch to a 
MD5 generated on the C string that is to be compiled and the cached MD5 
for the expression.  This would mean that only changes to that string 
would force a re-compile.  However, even formatting changes (even to 
whitespace) in the C string force a recompile.

As I'm not that familiar, this could be just hear-say.
