common data warning message

[wlandau]

When common data is large, I see a message like:

Warning in (function (...)  :
  Common data is 42.8 Mb. Recommended limit is  (set by clustermq.data.warning option)
Submitting 200 worker jobs (ID: cmq6272) ...
Running 1,200 calculations (13 objs/42.8 Mb common; 1 calls/chunk) ...

where the recommended limit is missing if the clustermq.data.warning option is not set. Would you be open to writing getOption("clustermq.data.warning", 1000) in this line?

clustermq/R/qsys.r

Line 82 in 7812577

"is ", getOption("clustermq.data.warning"),

Also, I'm a bit surprised that 42.8 Mb generated the warning if the default limit is 1000 Mb.
