Should this say to use runtest in an empty temporary directory because it will create many temporary files and not necessarily remove all of them afterwards? (I don't know whether it is safe to share that directory between simultaneous runs of the libstdc++, g++, gcc etc. testsuites.)

It is safe to share between runs, although probably not (due to testsuite lameness) not simultaneous runs. I'll add some additional verbiage.
