loooong lockup when editing ()

It's reaaaaalllly painful to have things you're 'forbidden' to type!

I just watched my heavy duty graphics programmer laptop spend upwards of 3 minutes
with pceEmacs locked up after typing 


onload_register(Generator) --> 
 html(js_script( 
   
      )). 

with the intent of typing something between those parens.

When it did come back I immediately typed '' because this is far from the first time
I've been stuck with this.

It always occurs when typing (), and started showing up after 7, presumably with the functional notation.
