if you are building for speed avoid $&, $' and $` as they make copies of
the variable being manipulated (see Freidl's Mastering Regular Expressions
ppgs. 273-278 and 281-282).
"you could try changing your substitute to a match and either using parens
with $1 $2 and so on or you could use
$& with $` (back tick) and $' (forward tick)"

i don't have time to work with this at the moment - but i can make a
suggestion:
why not change the goal from:
"I want to get rid of everything in between a leading and ending marker"
to...
"i want to keep everything before and after a leading and ending marker"
you could try changing your substitute to a match and either using parens
with $1 $2 and so on or you could use
$& with $` (back tick) and $' (forward tick)
