[Rd] R 3.4 and mclapply assertion failure - is this a bug?

Yan,

this looks like an interaction of OpenMP in data.table and forking - you may
want to report that to Matt as he can shed more light on that. He has been
complaining that we didn't enable OpenMP before 3.4 so he probably knows
about the issue and how to fix it.

Cheers,
Simon
