Filing report at Alan's request.
While this is grinding, I'll try to work up an isolated
test case that doesn't involve 20 tables.

Host's PHP is actually 4.2.3, but not believed to be related.

It probably a bug - the fetch() call should reset the 'has links been 
loaded flag..'

- can you file it as a bug.

can you turn debugging on and see what is happening.
It appears that the link_loaded flag is reset correctly in fetch.

I've checked the cache code - it appears to behaving as expected.. - eg. only reseting the cache if a update succeeds
- can you turn debugging on DB_DataObject::debugLevel(5);
and see what happens
