the cache I put in is shared between processes, so if you do "ls
/smb/foo" twice in a row the lookup is done only once. It is shared
both parent->child and child->parent. The existing code could do
neither.

also cli_reestablish_connection() is broken at the moment. I
fixed it a bit, but it still has problems.
