Roundtable

• need to find an owner for mysterious new trunk topcrash bug 545195
  • may be related to DLL blocklisting, although not sure
  • comes and goes daily/hourly, but when it's around it's the #1 trunk topcrash by a big factor

• firebot noise in IRC. probably time to avoid giving the status changes of each tinderbox tree. it's anti-social.

• sixgill results: http://sixgill.org/firefox/write_overflow/index.html

• Limi is looking for someone to help with [resources packages] which should help speed up web page load time. Being tracked in bug 529208, but needs a module owner to help shepherd it. Who'd that be?
