Queueing can be a good solution, but we should guarantee running  
in the arrival order to avoid starvation (see dining philosophers).

András made a good solution for this in run-webkit-tests implementation 
(--wait-for-http locking mechanism). The idea is very simple, the script 
touch a new lock.XXXX file, where XXX is an automatically incremental value,
and always runs the owner of least one.
