Shared hosting sucks
Textdrive (my shared-hosting company) kills my Typo process every few days causing regular blog outages. I finally gave up, and tried to export all my blog entries... Textdrive helpfully kills that before it completes because it's using too much processor time (the mysql interaction doesn't respond to the 'nice' command)
As soon as I get some time, I'm going to switch to some other hosted blog service... this is the worst of both worlds.
