FWIW, I figured out how to put the dumps into separate files by now...

Hm. I can see a few ways to deal with it. Are they running concurrently?
If not then it's easy enough to deal with.
It'd be a bit of a fight with cdb's awfully documented and quirky
scripting [1], but the best solution would probably be to just use an
environment variable from the target process to determine the dump
location. Then each buildfarm config could set a BF_BACKTRACE_LOCATION
variable or such...
[1] So there's !envvar. But that yields a string like
BF_BACKTRACE_LOCATION = value of environment variable when set to an
alias. And I haven't found an easy way to get rid of the "variablename
= ". There is .foreach /pS [2] which could be used to skip over the
varname =, but that then splits on all whitespaces. Gah.
