This test set up two posix timers with different clocks: REALTIME and
MONOTONIC.
Both send signals.
Signals are disabled before suspend. This makes overrun counters increasing.
After restore tests enables signals, and make sure, that:
1) signal handler for both timers was called with proper arguments
2) time displacement for both timers is not greater than specified (10% by
default).

We don't need to umount each points one by one,
if we are goning to do pivot_root().
"""
pivot_root moves the root file system of the current process to the
directory put_old and makes new_root the new root file system.
"""
So I suggest to do pivot_root() and then detach the old root, all
other mount points will be unmounted automatically.

The test creates two processes.
A first process creates a tcp server, a second one connects to it.
The first process is dumped and restored.
Then the test checks that the TCP connection is alive.

The test is tricky -- it opens master in task 1
and dup it in task 2, then close in task 1 and
do C/R.
Thus we need to setup SID of master terminal
somehow in children, which usually fails in
currnt tty restore implementation.

The problem is to get a virtual pid for zombies.
This code gets two list of children from current and target pidns.
Then it removes alive task from the second list and dumps remaining zombies.
