[R] Snow/Snowfall hangs on windows 7

[Uwe Ligges]

Folks,

I guess I know what is going on (and why I haven't seen this so far): 
All of you have installed R in a directory with blanks in it, right?

Please source() the attached sock.R and afterwards try again. Does it 
work with SOCK clusters now? Then it was just the lack of quotes.

CCing Luke the diffs (against snow 0.3-3 on CRAN):

(same problem in mpi.R, nws.R etc. as well, I think)

Best wishes,
