This is not completely true, as of 8.2 there is an online index build,
and if that could be used in a background thread to rebuild the index
and replace the bloated one once it's finished, that would be a
non-blocking operation which could be done in 24x7 situations.
There are some issues with using the online index build for replacing an
existing index, but if those could be solved it would be a viable
solution I think...
