#72 print msg after switch is created

[Stas Sergeev]

Currently there is no way to find out
when vde_switch created a socket. So if
some program starts vde_switch (using
pipes for stdio) and then, say, vdeslirp,
the vdeslirp may fail because the control
socket is not yet created.
Instead of using sleep(1) in the program,
I propose the patch that prints the message
as soon as the control sock is created.
