The only unusual thing strace shows is thai it calls rt_sigprocmask()
hundred times. rt_sigprocmask() stops irqs for a very short time. A
prog that calls it 1M time shows this is not what I'm looking for.
I searched in all /arch/ppc for something interesting... nothing. I
definitely need a tool to measure how much time the various
spinlock_irq's are hold.

strace libtool shows 13 lines like this:
mmap(ptrace: umoven: input/output error
) = 0x30019000
I don't know what does it mean.
Bye.
