Race condition on parallel package's mcexit and rmChild
...n = write(master_fd, &len, sizeof(len));

}
So a pipe write is made in mc_exit, and here's how this function is
used in src/library/parallel/R/unix/mcfork.R:
mcexit <- function(exit.code = 0L, send = NULL)
{
if (!is.null(send)) try(sendMaster(send), silent = TRUE)
.Call(C_mc_exit, as.integer(exit.code))
}
Between sendMaster() and mc_exit() calls, which are made in the child
process, the master process may call readChild() followed by
rmChild(). rmChild closes the pipe on the master side, and if it's
called before child calls mc_exit, a SIGPIPE will be raised when chil...
