Hi Jelmer,

nice that you share my opinion - which I've stated already. We really 
need to do some performance improvements on "make test".
Have I understood it correctly that part of the problem lies in the 
"fsync"s in the LDB transaction code? Probably we could add some bypass 
code for them when run under "make test".
