Hi,
    I'm new to the list, hope my question is not a FAQ.

    The problem is with the nanosleep call, who is very very long. On 
the host,

laita:~# time sleep 1
real    0m1.004s
user    0m0.000s
sys     0m0.004s


That's seem normal to me. But on the uml host:

douron:~# time sleep 1
real    1m22.724s
user    0m0.000s
sys     0m0.000s

it is very very long! Problem occurs whith all nanosleep system call, ie 
vi call nanosleep to make the screen blink.
Despite of this problem, performance seems normal, but each time 
nanosleep is called, there's a performance probleme.

I'm running kernel  2.6.17 patched with skas 3-1, on a debian sid.

Thanks for help
