This isn't in 2.1.1 yet. :-(  It's one of the reasons we're considering
2.1.2.

It can cause core dumps on certain cases using continue inside try.
Here's an example, from 

http://sourceforge.net/tracker/?group_id=5470&atid=105470&func=detail&aid=463359

#!/usr/local/bin/python
args = [1]
print "MAIN:", args
while 1:
    print "TOP OF LOOP"
    try:
        print "args:", args
        if not args:
            print "break"
            break
        i = int(args.pop(0))
        print i
        continue
    except:
        print "RAISE"
        raise
print "DONE"
