- File src/os_unix.c — part of check-in [35625961] at 2012-11-13 10:54:12 on branch tkt-5eaa61ea18 — When available, use posix_fallocate() rather than ftruncate() to allocate space for mmap()ed -shm files, since posix_fallocate() gives an error if no disk space is available whereas ftruncate() is silent and leaves the system vulnerable to a SIGBUS upon first write to the mmap()ed region.
