Rather than a simple counter, why not hash tracebacks so they are not sent more than once?  For example:

from twisted.python.failure import Failure
import sha

def a(): b()
def b(): c()
def c(): raise RuntimeError()

def fail():
    try:
        a()
    except:
        return Failure()

def fhash(f):
    return sha.new(
        f.getTraceback(elideFrameworkCode=1, detail='brief')).digest()

f1 = fail()
f2 = fail()

print fhash(f1) == fhash(f2)
