Moz2 mini farm implementation

bhearsum is going to be working primarily in Build for the next 1-2 months.

- Working on Try server Talos, Vista slaves, baselines is on the back burner for now.
Discussion over Talos/Tbox stability
- Much more stable - planned to add the tests to the production tree in 1 month (11/3)
- ~~blocked on bug 393338~~
- xml parsing bug re: svg - leaving this test off as it's unstable
- initial setup done, changes, very close
- pushing out to 11/14
Talos on the try server bug 398192
- The Buildbot side is moving quickly, I've already run a couple of test slaves.
- Managing/interpreting the data will take longer to figure out.
- robcee has machines and passwords, pushed off for production perf stuff
- punt for 2-3 weeks due to other priorities
Leak/Mochi tests on debug builds
- coop's item
- tracking bugs: bug 397724, ~~bug 374822~~, bug 397725

- Ben/Robcee to look at numbers
- still not resolved, justin to follow up
- pav says numbers are back to normal - resolved?
js test integration into talos
- crashing the browser

Txul platform differences according to mac mini machines
- mac: slowest on 1.8, slower still on 1.9 (30% regression)
- windows: fastest on 1.8, now in second place (30% regression)
- linux: middle on 1.8, now fastest on 1.9 (30% improvement)

dtrace status
- in, use --enable-dtrace on Solaris and Leopard.
- need to figure out how we're going to ship this (is it enough to build with the header file on 10.4, or do we actually need 10.5's compile-time linker?)

Followups
- sessionStore is really slow -- bug 398807 -- checked in, remaining issues marked blocking-, does this need to be tracked any more?
  - waiting for native json serializer to land
- force cycle collection in between page load in talos (bug # needed)
  - TODO: vlad -- figure out what's going on there (with jonas)

Firefox front-end perf
- sayer to put list of tasks on wiki
  - focus on measurements on tabbrowser reduction
  - Performance:FrontEnd
- dolske will do some profiling work
