The multi-pack-index subsystem was not closing its file descriptor after memory-mapping the file contents. After this mmap() succeeds, there is no need to keep the file descriptor open. In fact, there is signficant reason to close it so we do not run out of descriptors. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
