Both filesystems -- being written from and being written to -- have plenty
of space left. Linux gets peculiar when you get near 95% full, but both the
source and target filesystems were at less than 60%.

That's a clever thought! But df -i tells me that I have no more than 15%
usage of the inodes. So that doesn't seem to be it either.

Could be. I'll run some tests on the drives in question; I suppose a hiccup
on one of them could produce the rsync / ssh "freeze" in question. But there
isn't any trace in the logfiles of disk error. Time to run some read/write
tests.
