Seems the chances might be better than I expected... after the builds 
ran successfully using py_make_scanner the object_state table looks like:

2|last_build|1322571600.0
4|last_build|1322575200.0
3|last_build|1322582400.0

I don't know how those numbers are generated (e.g. if it was using 
time.time() I wouldn't expect it to be that exact), but normally those 
builders run on the hour... however a few days ago buildbot died over 
night (a separate issue heh) which meant the builders ran when we 
restarted it in the morning, and I guess they picked up the non-.0 
ending states at that point.

So... I guess this is just to wrap things up in case anyone else ever 
runs into this problem, since this is really a problem with simplejson 
rather than buildbot, and actually seems to have been fixed in more 
recent versions.

Our buildbot server is running Unbuntu 10.04 LTS which has a broken 
simplejson:
ii  python-simplejson               2.0.9-1build1                     
Simple, fast, extensible JSON encoder/decode

However I tested on another of our servers running Ubuntu 10.10 and the 
problem seems to be fixed in this version:
ii  python-simplejson               2.1.1-1                             
simple, fast, extensible JSON encoder/decoder for Python

Anyway thanks for the help and for pointing me in the right direction.
