Here’s a screen shot of the error the second MinTTY gives on trying to exit:

The “man bash” is the command I tried to give, and the “vi” command never executed, even after closing the first MinTTY window.  The defunct “less” process is of course a child of the “man” process.

To be clear, I mean bs=64k count=64M, for 4 TiB of transfer.  This ran for about half an hour before it started causing problems in the other MinTTY window here.  I didn’t write down the amount transferred at that time, unfortunately, though dd did report it.  Almost certainly many times more than available RAM at any rate.
