So even what I thought was still "good enough" isn't, really...
Hardly surprising, given that it's unmaintained for the last few
years.

Is this perhaps due to parsing the GDB/MI output?  Did you try to

the built-in JSON available with Emacs 27 could help (assuming that
profiling points to that as a hot spot)?
