(I'm a programmer but know nothing of svn internals, so take the idea and
lose the details)
(I also realise that this is more dev-list oriented, but I'm not subscribed
there...)
Wouldn't it be possible to do the deltification after doing the commit and
respondig to the client?
The commit is already operating in some thread, so why not use that for a
while longer and re-order the actions?
Something like the (stupidly written) example below.
Even the post-commit hook could be moved to run after sending the response
to the client. Its results do not affect the commit anyway (IIRC).
