In codepaths where we are likely under memory pressure, the above
might help, but I have to wonder
(1) if update-server-info and daemon fall into that category; and
(2) if Git continues to work under such a memory pressure to
cause even fdopen() to fail.
In other words, I do not see a reason not to do this change, but I
am not sure how much it would help us in practice.
We call fopen() from a lot more places than we call fdopen(). Do we
want to do the same, or is there a good reason why this does not
matter to callers of fopen(), and if so why doesn't the same reason
apply to callers of fdopen()?
