OK, the man page is not yet available on lenny.
Have you tried to kill the process using SIGKILL? What happens if you
do? I assume this behaviour is related to the state TASK_KILLABLE which
was introduced in kernel 2.6.25. In previous kernels a process waiting
for I/O was in TASK_UNINTERRUPTIBLE and never get the signal you send
it.
