Git generally does not explicitly close file descriptors that were open in the parent process when spawning a child process, but most of the time the child does not want to access them. As Windows does not allow removing or renaming a file that has a file descriptor open, a slow-to-exit child can even break the parent process by holding onto them. Use O_CLOEXEC flag to open files in various codepaths. * ls/git-open-cloexec: read-cache: make sure file handles are not inherited by child processes sha1_file: open window into packfiles with O_CLOEXEC sha1_file: rename git_open_noatime() to git_open()
