Potential for temporary file vulnerability in some circumstances. Some
older Unix-like systems create temp files with permission to write by all
by default, so be sure to set the umask to override this. Also, some older
Unix systems might fail to use O_EXCL when opening the file, so make sure
that O_EXCL is used by the library (CWE-377).
