squid async-io with debian-unstable problem

[Ling-En Kao <lekao@CCCA.nctu.edu.tw>]

Hi.
I am running squid-2.5STABLE7 on a debian-unstable box with
libc-2.3.2.ds1-18 installed, configured with
1024 aufs_threads.

But I only see one entry under "ps -auxH", while other threaded program
(I tried oopscache, bind9.) shows multiple threads under the same
command.

I've also tried linuxthreads and nptl by setting LD_ASSUME_KERNEL,
but still see only one entry under ps.

Is there something I omitted?

PS:
The box is running a 2.6.8.1 kernel, with libc6-i686 installed.
