[R-sig-hpc] foreach progress bar?

[Stephen Weston]

I've never done anything quite like that.  To get progress information
from foreach I've either used the foreach ".verbose=TRUE" option,
or displayed progress messages from a custom ".combine" function.
However, the ".combine" approach is only useful if you're using
a parallel backend that returns worker results on the fly, such as doMPI.
Using backends like doSNOW or doMC, the .combine function is
only called once, which isn't very useful for progress messages.
