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

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?
