weird result: sigconcept 41 UNRES (sometimes)

The sigconcept 41 test sometimes goes unresolved.
Does anyone know what this is?  I don't find any
current records of an analysis on the website, but
in googling I notice this has cropped up in various
journals for a long time - I see mentions of tests
on Debian that saw this (LSB 2 testing) back in '03,
we see it in the lsbsi for both LSB 2 and LSB 3, 
it's on the wiki as an unalayzed result in several 
configurations.

It doesn't seem to always occur, my own memory is
that I've had the fail on a specific machine/config
and rerun the test and not seen it, and vice versa
so it's possibly transient.  The lsbsi results record
it as only happening on /some/ architectures, but
other results also record only /some/ but a different
set, so I think this is another indiciation of the 
unpredictability, not arch-specific issues.

Anybody have anything useful to share?  Something
we concluded, didn't write down, and I've forgotten?

When this happens, the journal records the testcase
was sent a signal which should have stopped it,
but did not. When the problem happens, it always
looks like the journal snip recorded in the
wiki page:
