This is, unfortunately, contrary to what I was hoping.

What I hoped was that ecasound could time-stretch or -compress 
independent of pitch-shifting. At the very least, I thought there might 
be a way to simultaneously slow or speed playback while pitch-shifting 
to compensate. But this is a kind of windowed operation that ecasound 
probably doesn't have.

Better for me to investigate CSound, I guess. Or Pure Data, but it 
doens't make for a very good batch-processor.

The time-stretch and -compress options in Ardour seem to be pretty good 
[although they also tend to crash Ardour if you aren't careful], but 
Ardour is an even worse batch-processor than PD!!!
