No, this also has to done in Unix systems, because of dlopen() which
functions strictly based on filenames. In other words, if file foo.fas is
loaded it will refuse to load it a second time. Depending on the operating
system it may also refuse to load symlinks. And in some Unices I have found
that loaded files also can not be deleted. Unfortunately POSIX does not
specify any of this and thus the current system seems to be the only
foolproof one.

Ideally, this should not be a problem. ECL uses mkstemp to determine
temporary file names and the operating system is guaranteed to provide
unique names in a way that multiple processes can coexist.
