> The {{std::filebuf::open()}} function implements, as an extension, the ability to create
a temporary file that is automatically deleted on process exit (regardless of whether the
exit is normal or otherwise). The function uses the [mkstemp|http://www.opengroup.org/onlinepubs/009695399/functions/mkstemp.html]
function on POISX platforms and [tempnam|http://msdn.microsoft.com/en-us/library/ms235370(VS.80).aspx]
function on Windows. In both cases, the function uses the {{P_tmpdir}} macro for the directory
where to create the temporary file. On POSIX systems it's customary to be able to set the
{{TMPDIR}} environment variable to a directory where temporary files should be created by
programs. We should change our implementation so as to honor this convention. On Windows,
there is an analogous environment variable {{TMP}}. We should change our implementation on
Windows to honor {{TMP}} if it's set and use {{P_tmpdir}} only when it's not.
