@magicus unfortunately that is often not the case in practice. We can see many 
tests that normally run very quickly but occasionally run very slow - minutes 
versus seconds.

For this exercise existing explicit timeout values need to be multiplied by 4 
to keep the same absolute timeout value. In addition a number of tests that use 
the implicit default timeout (120*4) now need an explicit timeout (480 
generally).
