gsub uses regular expressions in a thread-unsafe way, because gsub
uses a the non-thread-safe interface.  ts_regex.gsub gets around this 
by serializing all gsub calls.  You must use a regex regular expression
with gsub, not a ts_regex regular expression.  Just make sure that
regular expressions used with ts_regex.gsub are *only* used with 
ts_regex.gsub.

Here's an example:

  import regex, ts_regex

  r=regex.compile("...")
  
  ...

  x=ts_regex.gsub(r, foo, bar)

Note that early versions of ts_regex did not have this problem
because they were not thread safe.
