mkdtemp is in glibc, and is documented:
  "The directory is created using mode `0700'."
If it doesn't do so, due to the umask, you can file a bug for glibc.

You are free to add a close_stream_temp function to the create-temp module
if you protect it with #ifdef so that it doesn't introduce a module
dependency.
