One likely reason for fdopen() to fail is the lack of memory for

This change was suggested by Jonathan Nieder [1]
In the first patch it is unsatisfying that try_to_free_routine() is
called with a magic number (1000) rather than sizeof(FILE). But the C
standard doesn't guarantee that FILE is a complete type, so I can't
think of a better approach. Suggestions, anybody?
it's not the sizeof(FILE) which is critical, it is the size of the buffer
associated with a FILE

BUFSIZ may be your friend, and if it is not defined, 4096 may be a
useful default.
