Re: [PATCH] Bug: fragile org refile cache

[Samuel Wales <samologist@gmail.com>]

long ago i used to use the refile cache.  i think it is probably not
widely used, or maybe even not at all.

the reason i stopped was behavior that sounds similar to your
description.  such as, it would produce a set of results that did not
match the calling conditions.  i cannot reach the thread you point to,
however.

what i did was use ido-hacks to speed up ido and restrict to :goto:
and :refile: tagged entries for common targets.  this worked for me;
it is fast despite my huge set of olpaths.  it would be great if the
cache were unnecessary.

that might nt work for you, but perhaps this provides confirmation or
ideas for you.
