Hello again,
resending mail, this time with involved people on CC and with clearer message.
I believe there's a bug in git-svn dcommit.
If during dcommit someone else commits to svn repository then git
a) stops
b) loses commits not-yet dcommitted
"a" is bug IMO, because it seems to work sometimes (only for first
dcommited change?)
"b" is more severe, because it destroys user data (in a way) - you
have to use reflog to get it back, I believe.
I have reproduced it locally - added "sleep" to git-svn in the dcommit
loop and did svn commit when it slept.
Pasting log from dcommit below. Notes:
- local git commits and unfetched svn commits were not conflicting
(changed different files)
- when starting dcommit there was one unfetched commit (r4) - this
worked without problems
- new change commited to svn was r8 - during sleep after r6
- "git log remotes/git-svn.." shows nothing => commit history is lost
- "git diff" shows all not-yet-commited changes merged in working tree

I'm also attaching "sleep" patch, logs from creating/commiting to svn
repository and from git svn clone for convenience (some messages from
svn are in Polish but that shouldn't matter)
