Oh, and if you would like to reproduce using your own build, Thunderbird build
instructions can be found here:
https://developer.mozilla.org/en/Simple_Thunderbird_build

I am building with the following .mozconfig file in use:
ac_add_options --enable-application=mail

ac_add_options --enable-debug
ac_add_options --enable-debugger-info-modules=yes
ac_add_options --enable-extensions=default,inspector
ac_add_options --disable-optimize

ac_add_options --enable-chrome-format=symlink

# BAD BAD BAD, but I don't like crashes :(
ac_add_options --disable-accessibility

mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-thunderbird-debug
mk_add_options MOZ_MAKE_FLAGS="-s -j6"


If you want to recreate the full experience:
hg clone http://hg.mozilla.org/users/bugmail_asutherland.org/tb-test-help/

The log file I previously attached already tells you what the actual stap run
arguments were.  Unfortunately at least the -x part is somewhat hard to create
because my wrapper script does its own variation on '-c' by forking a thread. 
(I think staprun was destroying my environment so xpcshell failed to run and
that was my workaround... although I think there were other pipe benefits to
that strategy.)

Once a build completes, I...
a) change to an output directory where I can run my unit test
cd obj-thunderbird-debug/mail/base/test

b) run my unit test with my test framework thing:
make SOLO_FILE=test_viewWrapper_virtualFolder.js EXTRA_TEST_ARGS="--debugger
/home/visbrero/rev_control/hg/tb-test-help/systemtap/chewchewwoowoo.py
--debugger-args
'/home/visbrero/rev_control/hg/tb-test-help/systemtap/mozperfish/mozperfish.stp
--'" check-one
