Sorry for asking, what is "FPC's tmt1" ?

I wonder whether it would be possible to patch affinity support into the
underlying TThread object? OTOH I'm currently looking at FPC's tmt1 running
under Linux on a 14-processor system and I can see it being spread fairly
evenly, so this is getting pretty specialist.

On linux you could use sched_setaffinity, but I don't think fpc has
wrapped that yet. Linux man page says it's linux specific.
tmt1 is part of the test suite when FPC (Free Pascal, the compiler that
underlies Lazarus) is built. Specifically, it tests threading and was broken
until comparatively recently on SPARC and possibly some other non-x86
platforms. I'd fired a big Sun up to specifically to check something related
to that program, so it was obviously no effort to look at the CPU usage after
noticing your query.
Apologies to everybody for the earlier top-posting. I alternate between
environments where the different conventions are appropriate.
