I've figured out that there was indeed an infinite recursion, but *my*
fault.
Running under Linux, I foolishly had a reflexive soft link somewhere in my
non-code files:
    /home/time/Desktop/Home -> /home/time
and when the DirectoryScanner went piling into the Desktop directory it kept
looping around those links until it ran out of memory and died. In this
light, the above symptoms are entirely explicable.

Solution: Don't use recursive soft links under UNIX environments.
I tried excluding the "Desktop" directory but gave up messing about after
several variations didn't work. Recursive sym links are bad practice anyway.
Mea culpa!

Thanks for the zen-inspirational help
