The only issue I'm aware of is that espresso-mode syntactically  
fontifies the whole buffer
when starting up to ensure that regular expressions are marked  
correctly. The comment
that explains it is here:

   ;; Important to fontify the whole buffer syntactically! If we don't,
   ;; then we might have regular expression literals that aren't marked
   ;; as strings, which will screw up parse-partial-sexp, scan-lists,
   ;; etc. and and produce maddening "unbalanced parenthesis" errors.
   ;; When we attempt to find the error and scroll to the portion of
   ;; the buffer containing the problem, JIT-lock will apply the
   ;; correct syntax to the regular expresion literal and the problem
   ;; will mysteriously disappear.
