cache coherency and transaction guarantees are problems which are known 
to be difficult to solve.  Long term, the RIPE NCC probably needs to aim 
for the degree of transaction read consistency that might be provided by 
an ACID database or something equivalent, and that will take time and 
probably a migration away from a filesystem-based data store.

So the question is what to do in the interim?  The bash script that Job 
posted may help to reduce some of the race conditions that are being 
observed, but it's unlikely to guarantee transaction consistency in a 
deep sense.  Does the RIPE NCC have an opinion on whether the approach 
used in this script would help with some of the problems that are being 
seen and if so, would there be any significant negative effects 
associated with implementing it as an intermediate patch-up?
