Sorry for bringing this up for attention at such late notice. However, shouldn't this be a configurable setting in riak?

Hi, Mat.  Is your reduce phase implemented in Javascript?  If so, it's subject to a hardcoded five second timeout in erlang_js.  Each Javascript call a MapReduce query makes must finish in under five seconds, regardless of the timeout set for the whole query.  Phases implemented in Erlang are not subject to this restriction.
