Especially since the nsapi docs for systhread_start only tell us that
the prio is an int depending on the platform and the only other source
of information, nsapi.h only contains a single defined prio, which is
SYSTHREAD_DEFAULT_PRIORITY.

The other constants PR_PRIORITY_... are defined in nspr/prthread.h and
are enum elements of type PRThreadPriority which formally don't qualify
as arguments to

systhread_start(int prio, int stksz, void (*fn)(void *), void *arg)

which needs an int.

I'm still not fully convinced, that PR_PRIORITY_* is correct and isn't
just working because PR_PRIORITY_NORMAL=1 is such a low number.

When you use PR_PRIORITY_NORMAL, can you see which priority the created
thread actually has? Probably using truss, since I think the thread
doesn't live long enough to be observable using "ps" with the "-L" flag
for threads and adding "pri" to the output format.

Nevertheless opening a bugzilla seems to be OK for tracking our progress
on this and making the problem publicly available. We might later decide
on resolving it as invalid though ;)

Well known problem, though I'm positively surprised you got such a
technically precise answer.

Rainer
