I'll probably disappear again soon, the traffic levels are rather
high :-) But I'll be back from time to time.

None of those reference /cygdrive/a or A:

Hmm, strange.
strace ruby -e 'puts Dir["/cygdrive/c/*{.txt,.bat}"]'
doesn't touch the A drive.  I wonder.  I'll have to strace the 
program I'm running, itself.  Probably something messes with the
definition of glob.

It's ferret_helper, from Stuart Rackham, which I've modified in other
places but nothing directly to do with Dir[].

Does Symantec Endpoint Protection do that?  Why not for the short
example?  It will take me a while to figure that out!
