For ZDTM purposes, poll.c uses delta of 5 seconds, which is fine, since
tests don't take a very long time to pass. However, in vzt-cpt, we start
a batch with multitude of tests and starting them all could take over an
hour. Hence, the test is bound to fail. An easy solution would be to
introduce an environment variable, which would allow to specify the
delta - ZDTM_DELTA. If it's unset (which is default behaviour in ZDTM) -
it would default to 5 seconds. However, if it's set (what we can do from
vzt-cpt) - then it will use delta which is set by our test.

A unix socket can be bound to itself, so we need only one socket
instead of a pair of pipe.
If we use a socket, we can peek a message and if it isn't for us
we don't need to send it back.
Currently a process reads message from pipe, if it isn't for him,
it sends it back and sleeps for a random timeout. In a worst case
each waiter will read and send a message back, before the right
one will get it.

By default, sockets03 doesn't set SIGPIPE handler to SIG_IGN. When run
by zdtm.py, it doesn't cause problem, because it inherits signal
handler. However, when run via vzt-cpt (which uses system() to launch
tests), it receives default handler (which would terminate test). As
result, test is guaranteed to fail, because it will attempt to write to
shutdown receiver and get SIGPIPE in the face.
