Very kind of you, applied!

Hmmm. Yet another variant of Linux, but of course, now you can't get a 
basic text only installation unless you download all four CDs.

Since the query runs on a different connection to the one which made 
the change, this suggests that the cache on the readonly connection 
isn't noticing the change to the file on disc.

This is probably down to the resolution of file times, which is what is 
used to detect these changes. Look in RaidFileUtil::RaidFileExists() in 
lib/raidfile/RaidFileUtil.cpp and try enabling the PLATFORM_LINUX code. 
It's not nice, but then, Linux isn't nice either.

Suggestions for a better way of achieving the same thing would be 
gratefully received. In real life use this is unlikely to be a big 
problem, which is why I haven't done too much work on making it better 
so far.

You are trying them in a sensible order. Thanks for doing all this work 
for me. :-)
