Yes, you are right, but in textops case the compiled regexes live as
long as ser so we don't need to free them. The regexes are compiled only
once, on ser/module startup (fixup_* functions) (they are not compiled
before each use). It would probably look nicer to free them from the
textops module destroy functions, but this would have only an estetic
value since this function is called only when ser exits.
