Very interesting. After some unknown action (possibly involving
restarting IDL), it seems as if it works now, with the exact same
command that was not working before. Has anybody else run into issues
like this? Any system or IDL level variables that would cause
something like that?

I should also mention that this does work:

IDL> spawn, 'cmd.exe', unit=unit
IDL> printf, unit, 'echo blah'

which yields no error, and I can then read from the pipe with no
issues.
