There used to be some benefit to setting it higher for large Emacs sessions
(where GC can take a long time) since it would reduce the frequency of those
GCs. In Emacs-22, this is not needed any more because of the new
`gc-cons-percentage' variable which automatically causes the limit to grow
as the Emacs process grows, thus preserving a more or less constant
GC overhead.
Thank you Stefan for your clarifications.
Xavier
