threadunsafety

   This file is shared with all compilers. This means that if we don't access 
it with a proper locking 
   mechanism, the running compilers might crash or hang. I'm not entirely sure 
how to locking works over a NFS, but I'm quite sure that this is the culprit. I 
investigated it with Kellen a bit a few weeks ago and found some statements on 
the internet that apparently it's quite sensitive to interact with the 
statistic files because it is queried a LOT during the compilation time and it 
is being used to synchronize between concurrent calls.
