Easy: it hasn't climbed high enough up anyone's todo list for it to 
actually get fixed.

I suspect (with little supporting evidence) that this is partly due to the 
different ways people are using clusters in diverse applications. For 
instance, a lot of the academic work is directed at microdecomposition via 
message passing, distributed shared memory or what have you. We on the 
other hand are currently doing some environmental modelling work 
characterised by large numbers of 30hr runs of a fat nasty FORTRAN program 
on assorted datasets. Clusters are appropriate in both cases, but different 
infrastructures are appropriate.

One indicator I don't much like is that there doesn't seem to be much 
cluster-related software among the thousands of ports in the ports collection.
