Please describe the problem.

When stall detection is enabled, debug output for transfers with external special remotes appears to be hidden.

What steps will reproduce the problem?

git config annex.stalldetection true
git annex copy file --to=externalspecialremote --debug 2>&1 | grep PROGRESS
# no lines output

What version of git-annex are you using? On what operating system?

I'm on RHEL7 and this problem is present in git master for me ever since the introduction of stall detection: 135757d64 through 4d6f74477

Please provide any additional information below.

# If you can, paste a complete transcript of the problem occurring here.
# If the problem is with the git-annex assistant, paste in .git/annex/daemon.log

# End of transcript or log.

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

I've written ESRPs and recovered many lost files =)
