[Rd] Error in close.connection(p) : ignoring SIGPIPE signal

[Benjamin Tyner]

Not sure if this is a bug, so posting here first. If I run:

    cnt <- 0L
    while (TRUE) {
        cnt <- cnt + 1L
        p <- pipe("echo /dev/stdin > /dev/null", open = "w")
        writeLines("foobar", p)
        tryCatch(close(p), error = function(e) { print(cnt); stop(e)})
    }

then once cnt gets to around 650, it fails with:

    [1] 654
    Error in close.connection(p) : ignoring SIGPIPE signal

Should I not be using pipe() in this way? Here is my sessionInfo()
