[PATCH 0/5] Retry if fdopen() fails due to ENOMEM

[Michael Haggerty <mhagger@alum.mit.edu>]

One likely reason for fdopen() to fail is the lack of memory for
allocating a FILE structure. When that happens, try freeing some
memory and calling fdopen() again in the hope that it will work the
second time.

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?
