I doubt it is related to regular expressions in your custom grammar, as 
these run in a separate thread.

It could either be that you have a command running “on document 
changes” or possibly that you are out of memory and the delays are 
causing by swapping memory out to disk.

When a delay happens you can run `sample TextMate 1` in a terminal to 
see what TextMate is doing.

You may want to make an alias or bind this to a hotkey, so that you can 
do it the instant you noticed that TextMate stalls.

You can also try to (install and then) run `pstree` when it is stalling 
to see if there is any subprocess being run by TextMate.
