Open a longer html file like this:
http://web.netbeans.org/struts/struts-support-ui-spec.html and try edit it.
Every 2 seconds after typing is started code folding process, which takes 100%
of processor and more then 30 seconds for one cycle.
Will you Marku mark this as duplicate of #55541 ? The workaround is to avoid
using unclosed tags and/or disable code folding feature.
It is 4.1 problem.
There has been done some fixes recently - see issue #55541. Moreover the fold
computation code will be rewriten in 4.2. Thanks for your disaster report :-)
