Running tests at high parallelism on a slow machine, 5 sec is not enough to wait for p4d to start. Change it to 5 minutes, adding an environment variable P4D_START_PATIENCE to shrink that if needed in automated test environments. Also check if the pid of the p4d that we started is still around. If not, quit waiting for it immediately. Remove all the confusing && chaining and simplify the code.
