A year or two back I was having some odd cache issues with the stable
client.  I hacked the init script (This is Gentoo, by the way.) to clear
the cache each time right before starting the client.  That solved my
problems back then, and at some point the init script got overwritten by
an update.  But by then my cache problems were gone, so I didn't worry
about it.  It's certainly easy to put back in.

I'll certainly try clearing the cache.  But I'm also guessing that I'm
also talking to a greater-than-average variety of servers, and wondering
if there could be a vintage problem here.  Is there a way to query a
mount point to find the server version providing that data?  (Or perhaps
there's other relevant information to query.)
