APP CRASH (unit_tests DesktopNotificationsTest)

_From [bruen...@google.com](https://code.google.com/u/109494838902877177630/) on March 10, 2011 15:27:27_

on my win7 laptop, when I ran sets of 50 tests this one worked.
but running from start it has a lot of failures and then the process exits.
I had a native unit_tests running, could that have messed it up?
after that run, later runs all worked on my laptop.

but on my win7 VM, this fails when run as part of the full suite.
when run by itself it works.

--------------------------------------------------

happened again on laptop, same circumstances with another unit_tests
running. but I can't seem to repro that by having one under DR at msgbox
mask (at startup: maybe needs to be partway through) while running another
one natively.
