There is a "cache flush" command in hobbitd_rrd, and the graph tool
does send a flush-command before showing the graph. However, the 
graph tool does not know when the flush completed, so it will 
just wait for about half a second before drawing the graph. So
you may see the graph while the flush is still in progress.

If that happens, you can usually just hit 'reload' in your browser.
By then the cache should have been flushed, and you'll get the full
graph.

There is an "rrdcachectl" utility, but it wasn't included in the
4.3.0 beta release. I've added it in the current release on the
Sourceforge source-code archive.

Henrik
