Replacetext taking forever under 8.1.7

Hi Bruce,

If the same code snippet takes 20 mins in 8.1.7 and 1 second in 7.1.4, this
is definitely a bug. Please do file a report in, and
make sure you attach a simple sample stack that demonstrates the problem
for you.
Regression bugs have higher priority, so I would expect this issue to be
addressed soon, once it is confirmed.
