I agree.

The alternative is to require any program which switches locations
using G__switch_env() to ensure that G_tempfile() doesn't get called
while the location is switched. Given that calls to G_tempfile() could
be hidden deep down in the call graph, that requirement would be
extremely hard to comply with.
