I'm not certain exactly what you're running into, but I do know that  
the way Drosera gets information about the script as its running is  
known to be slow, with too much information traveling cross-process.  
In some cases that may make it too slow to be useful, although it does  
seem fast enough in many cases.

I'd love to see improvements in Drosera.

PS: Long-term we would like to be able to do JavaScript debugging in- 
process rather than in a separate program -- that will require planned  
changes to the JavaScript engine to make it interruptible.
