actually i thought the same, but i had a look at send~-help.pd again,
and it clearly says, that [send~]/[receive~] pairs are only wokring with
a blocksize of 64 (updated last time for 0.33)

from my tests, it seems, that a block delay is not avoidable with
tables.

i found something interesting here. i was trying to find a solution, but
couldn't find something else than using [delwrite~]/[delread~] pair.
however, the interesting part is, that you only can get 0 delay, if you
really put them in separated subpatches wich are connected. even if the
creation order of [dekwrite~] and [delread~] is correct, the delay is
one block. or if you cut the connection between the two subpatches, the
delay jumps to one block again. and also make sure, to give [delwrite~]
at least a buffer of one block size~. [delwrite~ bla 0] doesn't work,
even if the resulting delay is 0ms.
