Hi,
There have been a number of issues regarding unit tests as of late - the 
main problem being that they are taking too long. The reason for the 
increased test time was using a file instead of memory. I have tried a 
number of things to improve the test times but to no avail (for example 
defining the pragma cache which I understand uses mmap for the file - 
this reduced the time of an average test from 4 seconds to 2 seconds. 
When using memory this was 0.10 secs). I have reverted them back to the 
in memory and suggest that we discuss on how to tackle the problem in 
the future. I think that it is better that we have the tests running and 
try and work on a better long term solution off line. I guess that we 
can discuss this at summit. Please look at -
