[Rd] cat cannot write more than 10000 characters? [R 2.8.1]

during the examination of a Sweave hang-up inside an odfWeave call (OOo
XMLs have looong lines) I have discovered that my cat function cannot
write more than 10000 characters to a text file. Otherwise, the internal
C code causes a hang-up, which can only be stopped with a quit signal
that terminates the R session. Is this behavior normal?

Code to reproduce this:

testChunk <- paste(rep("a", 10000 + 1), ## delete "+ 1" to be successful
output <- tempfile()
cat(testChunk, sep = "\n", file = output, append = TRUE)

My sessionInfo:

R version 2.8.1 (2008-12-22)
i686-pc-linux-gnu (actually the latest openSuse 11.1)

Thanks in advance,
