Oh... you're right, there's no good way to do that.  sys.path is
strictly global -- there's no way to change it for one context or
servlet (without bad import-hook voodoo, which isn't worth it).

I'm not sure if you're on Windows or Unix, but on Unix you could create
a symbolic link to the directory you want to include under say
/context1/www/ -- the other context could still do "import context1.dir"
and get to it, but in context one you could do "import dir" and get the
right directory.

Otherwise you can simply name things differently... what's the problem
you're trying to solve with this?  There may be a better way to do it.
