MacOSX10.4.11; R-2.6.1 (downloaded the dmg yesterday).

I am having difficulty with system().  In my case the unix command  
a single very very long line and my toy example appears to
hang R:

string <- "yes | sed 10q | tr '\n' ' ' "
a <- system(string,intern=TRUE)

in the R Console  R seems to hang and
I need to force-quit.

Things are better on a terminal but I still need to type control-C
to suspend the system() command.
