[erlang-questions] how can I access test_server_loc in the process dict ofanother process?

Thanks, I had missed that.
trace can do lots of things, but it won't tell you line numbers unless
I'm mistaken (assuming you've inserted them).
but i do agree that line numbers might be useless for profiling in many
cases, but it can be very very useful.

allow me to point out that what you're trying to accomplish can be
done (without recompiling/parse transforms) through tracing.
