Do you mean $! ? I wasn't sure $! would be reliable here. I actually
included $! as I was trying to figure out what was going on, and I got
a bunch of (seemingly) meaningless messages.

I'm glad you were able to translate that perldoc statement (which I
struggle to understand, with little success) into something that makes
sense! Thanks!

The die handler is designed to catch my own die() calls. I die within
my script under various dire circumstances, but I want to do some
housecleaning before I really leave (dispatching final logging methods,
closing databases cleanly, etc), so I use the handler. Maybe that's not
the best way to do it...
I didn't anticipate catching any die()s from Net::SFTP because the docs
for the module claim it die()s only in under fairly restrictive (and
unlikely) conditions. Your speculation about the module die()'ng inside
evals sounds plausable, and will make me re-think my exit strategy for
exception handling.
Thanks, Xho (and thanks, Sinan, for your amazing efforts to help also,
which were apparently thwarted by what seems to be a bug in Net::SSH on
Windows - but I'm a UN*X weenie).
