xvfb

                          The Travis CI documentation  says to run sleep 3 after starting xvfb to "give [it] some time to start". I couldn't find any reference to this delay in the man page . Is this cargo cult programming? If not, how do I **poll** rather than sleep to *guarantee* it's available?
