[Rd] Is R threadsafe?

[Kannan Ramaswamy]

Hi,
I am planning to embed R in a Windows application. I would like to know 
if the R.dll dynamic library is threadsafe? Is it possible to have more 
than one thread calling R functions concurrently? Note that I am using 
Windows XP SP2 with R 2.2.1 on a dual processor SMP machine.

The last information I found in the R-devel archives was a mail from 
Duncan Temple Lang on 07-Nov-2005 saying there was a plan to make it 
threadsafe before the end of the year 
(http://tolstoy.newcastle.edu.au/R/devel/05/11/3110.html).
