I just reverted icomplete-show-matches-on-no-input to nil, which I think
is the right default.  That it can take a long time to get the
completions is not in itself a bug.  There are 2 potential bugs left, tho:
- hitting a key should interrupt the completions processing (so that
  the long wait should not prevent you from getting work done).
  If it doesn't, then we have a bug.  Please report it separately, with
  as much details as possible to reproduce it (it's probably a problem
  in the C code).
- ideally completion should never take that long, so we probably have
  a performance bug somewhere.  Of course, that might also be in your
  local code (.emacs, icicles, ...).

[The build noted below is the one this bug report is for.  But I'm
sending this using an older build than the one noted below, because of
another new bug, which prevents using `report-emacs-bug']


Just a preliminary heads up for now.  Hope to add more info later, when
I get some time.

I downloaded this build, and when `icomplete-mode' is on, with my setup
it takes several seconds to gather the list of file candidates in my
usual directory.  With a build from two days ago, this does not happen.
And if I turn off icomplete mode it also does not happen.

It seems that something was changed in the icomplete mode code recently
that breaks at least my file-finding code.

With emacs -Q I do not notice the problem (well, maybe a slight delay).
I see that C-x C-f now shows completions immediately, without my typing
any prefix.  That is not true in the build from 2 days ago.
