(The point here is to maximize the amount of concurrency we can
simulate.  Down the road, the logging may become pre thread with
a final sorting pass to get all the messages correctly interleaved.)

This costs us an extra getsockname(2) call per connection, so default

SHM clients can tell the state of this option by the number of fields
in SessionOpen: 3 (off) or 4 (on).

Make an executive decision, and change the regsub() replacement specifiers to
get something which is consistent and nontroubling for URL and query strings.

Since $ and & both are heavily used in query strings, we (DES & I)
have chosen to use \0 ... \9 for replacement indicators, with \0
being the "all matched text" replacement and \1...\9 replacing
with tne N'th paranthesized subexpressions.
