Similar to #1751, the trace function doesn't report events for "with" statements:

$ cat bug.py
import sys

def tracefunc(frame, event, arg):
    print "Trace", event, frame.f_lineno
    return tracefunc

def do():
    with open("hello.txt", "w") as f:
        f.write("Hello\n")

sys.settrace(tracefunc)
do()

$ python2.7 bug.py
Trace call 7
Trace line 8
Trace line 9
Trace return 9
Trace call 38
Trace call 38

$ jython bug.py
Trace call 7
Trace line 9
Trace return 9
