kopia: kopia client gets stuck when creating remote snapshot

Version: 0.6.1

Hi,

tried to run kopia on two different Debian systems (x64), one instance in server mode, the other in client mode. The systems are in the same LAN, connected via GB ethernet. At some point, the client seems to get stuck:

root@ThinkPad-L450:~# kopia snapshot create /home
Snapshotting root@thinkpad-l450:/home ...
 - 3 hashing, 2677 hashed (1.1 GB), 589 cached (54.3 MB), 0 uploaded (0 B), 0 errors 100.0%

Nothing happening anymore after that point. I tried to run strace on the client process:

I unset GODEBUG and built latest git master. I can confirm that 27ec5c7 works for me as well.

Can you folks try:
$ export GODEBUG=http2server=0
$ kopia server start ...
I suspect there may be a bug in Golang http2 server, this should disable it.

Seems to do the trick. Thanks!

FYI - I filed a bug with golang/go.
