### Please describe the problem.

Originally reported (so more details could be found there) in [datalad issue #2988].

While trying to `annex get` on local cluster, over ssh without a ssh-agent, I was prompted for password multiple times, although previous version didn't do it:

[[!format sh """
[yhalchen@discovery7 QA]$ git annex version | head -n1 ; git annex get -J2 sub-qa/
git-annex version: 6.20180926-gc906aaf
get sub-qa/ses-20161128/dwi/sub-qa_ses-20161128_acq-DTIX30Xp2Xs4_dwi.nii.gz get sub-qa/ses-20161128/dwi/sub-qa_ses-20161128_acq-DTIX30Xp2_dwi.nii.gz (from origin...) 
(from origin...) 
yoh@falkor.datalad.org's password: yoh@falkor.datalad.org's password: 
"""]]


and when I try an "imputated" from NeuroDebian .deb package recent build of git-annex then I am observing

[[!format sh """
[yhalchen@discovery7 QA]$ export PATH=/ihome/yhalchen/7.20181105+git22-g4c7236c58/usr/lib/git-annex.linux:$PATH

so smells like may be recent fixes caused some other locking problems

This is on an NFS mounted partition, but remains the same when run under `/tmp` 

Running a significantly more outdated version I found laying around (6.20170815+gitg22da64d0f-1~ndall+1) shows a single password prompt
