Should HOME be used on a Unix system in preference to querying
someone's home directory via the UID/EUID of the process, and using
getpwuid() ?

What about using P_tmpdir from <stdio.h> if it's defined, rather than
/tmp?  Using /tmp on Solaris, for example is a bad idea, since that's 
your swap space.  At the very least, "/var/tmp" should be used.
