/**
 * apr_bucket_pipe closes a pipe's file descriptor when it has reached
 * end-of-stream, but not when an error has occurred. This behavior is
 * undesirable because it can easily cause file descriptor leaks.
 *
 * passenger_bucket is like apr_bucket_pipe, but it also holds a reference to
 * a Session. When a read error has occured or when end-of-stream has been
 * reached, the Session will be dereferenced, so that the underlying file
 * descriptor is closed.
 *
 * passenger_bucket also ignores the APR_NONBLOCK_READ flag because that's
 * known to cause strange I/O problems.
