Isn't the crux of the problem that there's no way to specify/predict
which thread should handle a signal?

Assuming that signal disposition is a per-thread attribute (big assumption 1)
and assuming that signal disposition really works on all platforms (big
assumption 2) we could ensure that the main (startup) thread got the signal if
we had epicsThreadCreate call sigprocmask to block signals in all created
(i.e. non-main) threads. Of course dealing with signals that arrived right
during the thread creation would probably still be an issue.
My recommendation to Bob Soliday remains, "try to find a way to deal with this
situtation that doesn't involve catching signals".
