data.tables, you say? Can you show us the NOTE message you're getting?
It could be that your example takes too much CPU time (as opposed to
"real", "wallclock" time) due to running too many threads started by
data.table.

It's not obvious why data.table would start too many threads (it's
supposed to honour the limits that CRAN expresses in environment
variables), but at least it should be easy to check and discount.
