I am thinking that falling back to getpwuid(getuid()) is the most reasonable

This fails when there are multiple users with the same uid as getpwuid()
will likely fetch the first matching entry. On FreeBSD (& May be other BSDs)
getlogin() is a syscall and works correctly without a controlling terminal.
But I was forgetting about Linux which never disappoints in disappointing.
I think use of $LOGNAME as a fallback may be good enough.
