Your usage seems to a very special case. You're closing the handle,
and then invoking the method "command_close_bidi_pipe", whose job is
to close the pipe handles passed to it (among other things). So, it
doesn't seem very good to make "command_close_bidi_pipe" to take into
account that you closed your handle independently.

Maybe you could write a pair of new functions for the commit-tree
command in the Git package, something like the
"_open_hash_and_insert_object_if_needed" and "hash_and_insert_object"
pair.
