sorry for sending this again - but until now i got
no answer to my question about the current state of
while-no-inmput - see below - maybe you have forgotten to
answer... ;-)

Done - after reading the whole thread i can say: I agree at 100% with you and Kim.
Such a macro would be very important especially for a program like Emacs which
has still not thread-feature like Java, C++ et. al. IMHO this is one of the
most important any annoying lacks of emacs-lisp and for programmers...
And i agree with Kim that especially people working with remote-paths and
packages which makes this completely transparent (like tramp, ange-ftp and efs)
would profite a lot from such a macro like while-no-input -
The current discussion how to enable tools like ECB to display some state-value
for files (as the VC-state-values) where the computation could be expensive
is IMHO a good example to demonstrate the need of such feature - so we have no
threads avaliable in emacs-lisp to perform such expensive tasks in the background
without blocking the user of Emacs but we could at least offer the users of
such tools a way how to easily (hitting C-g is not acceptable) interrupt also
"atomic" calls as call of call-process etc...
Well, Stefan - this thread was discussed in 2002 - what is current state of
this while-no-input???

Yes, see my discussion with Andre about this...
