Hi Andreas,
thank you very much, good job finding it was EBADF. Now the question is
why the pipe has been closed prematurely; it could be accidentally by R
(a race condition in the cleanup code in fork.c) or possibly by some
other code running in the same process (maybe the R program itself or
some other code it runs). Maybe we can take this off the list and come
back when we know the cause
