Yes.  And we do not rebase next lightly nor often (just check this
history how often this happened in the past).  But we explicitly
reserve the right of doing this to make sure we get the needed quality
of the code before pulling it into master, which definitely cannot be
rebased.  So instead of knowingly pulling blatant crap into master we
will rather make this exception and rebase next.

No.  Historically next was opened when -rc1 was released.  In theory
this would be at the end of the MW, but I always found myself with a
large backlog of patches tat were not picked up by any custodian trees
but left waiting, and I wanted to have these included in the -rc1,
which reasulted in the often week-long delay.

Provide more people processing patches, say pushing stuff through the
staging repo etc., and we can easily reduce this delay.

Best regards,

Wolfgang Denk
