I'll wager you're blocking and it winds up slupring in all output from  
that process.

There's one problem.  This input operator will block until it gets a  
newline.  You need to use sysread() to read whatever's available.  You  
*will* get partial lines.  That's fine for something that loads the  
text into a TextView.  If you really need full lines for matching,  
then you'll want to do framing yourself -- create an object to  
encapsulate each watch handler, and keep a state variable with the  
last partial line, to which you append on the next read.

Don't do that in an i/o watch handler --- just return control to the  
main loop.
