linux_threads nice bug ? nice / nohup confusion

[Martin Blapp]

Hi,

After closly looking at some of our mysql performance issues,
I've found out that all mysqld threads (I'm using linuxthreads)
are running at +14 niceness. This is of course a catastropy.

A renice of the main thread does not help. If I do that, I see
that all new created threads have again niceness +14. Starting
without nohup makes +11 as niceness.

I guess there is somewhere a severe bug here.

What do you think Tor ?
