------------------------
Example:
library(rgl)
library(parallel)
example(plot3d)
cl <- makeForkCluster(2)
a <- parLapply(cl, 1:1e7, dnorm)

now manipulate the rgl window (rotate, focus/unfocus, hide, redraw...) while R performs the calculations. R crashes with a messages like

[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
R: ../../src/xcb_io.c:274: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.

confirmed on ubuntu 14.04, RHEL 6.7 (remote over ssh)

I would be happy to include a tested patch to fix this, but I will not work on it myself.
