Thanks for the feedback. I know it is an important feature, and it is
there for a long time :) (see eg.
https://svn.boost.org/trac10/ticket/3484).

What would be possible at low/moderate cost would be to have thread
safety while inside a test case, where assertions and messages can come
from different threads.
Would that make you use boost.test?

In a second step, I can work on making the framework thread-safe such
that we can enable parallel test-case execution. This would be more
tricky because it involves more components.

I suggest we start easy.
