[Twisted-Python] dumb question on qt4reactor

[Kevin Mcintyre]

calling reactor.callLater within qt4reactor in an attempt to async non
webkit work but not seeing expected behavior.  Webkit locks while the
callLater function executes.

Any insight appreciated.

Should I move real work into separate reactor and "broker" calls into
qt4reactor/webkit.  I have xmlrpc and websocket  hooks into browser...but
looking for guidance as to most direct method of brokering calls between
reactors.

Any insight appreciated.

Having a blast using QT browser as a back-end, see demo site
www.athleets.com.

See below for amazon S3 upload worker that I expected to async, but in
qt4reactor does not appear to work as planned.

from pyscewpt import fixed
from pyscewpt.s3 import bucket_util
import boto
from boto.s3.bucket import Bucket
from boto.s3.key import Key

from twisted.internet import defer, reactor

bucket_queue = defer.DeferredQueue()

def upload_worker(data):
    print 'macth upload_worker', data
    save_match( data['league'], data['twitter'], data['local_file'],
data['meta'], data['profile'])
    return len(bucket_queue.pending)
def match_queue(ign=None):
    print 'match_queue:', len(bucket_queue.pending),
len(bucket_queue.waiting)
    if ign is None or ign >= 2:
        print 'requeue:', len(bucket_queue.pending) ,
len(bucket_queue.waiting)
        d = bucket_queue.get()
        d.addCallback(upload_worker)
        d.addBoth(match_queue)
        return d
    else:
        return None
def queue_save_match(queue_dic):
    bucket_queue.put(queue_dic)
    print 'queue_save_match', len(bucket_queue.pending),
len(bucket_queue.waiting), queue_dic['twitter']    #
    if len(bucket_queue.pending) >= 5 and len(bucket_queue.waiting) == 0:
        print 'queue drop worker'
        reactor.callLater(0,match_queue,None)

def save_match(league, twitter, systemfile, meta, profile):
    print 'save_match:', twitter, profile
    s3_filename = league + '/' + twitter + '.png'
    bucket_util.save_s3(
        boto.connect_s3().get_bucket('~bucket'),
        s3_filename,
        None,
        systemfile,
        'image/png',
        'public-read',
        meta + [('yes', False), ('no', False), ('maybe', False),
('profile', profile)]
    )
