This has been tested on a customer project and seems to work great (it 
may even have reduce test durations and memory usage).

It was implemented as a more compact 'retry-after-sleep' Ant macro, 
which may be brought to Yanel for general usage at some point as it is 
not project-specific at all.

This might now be implemented easily an as extra optional parameter to 
that macro, or in another similar macro.
