fatal bug on svn in core functionality reproducing every time

Bug title: Svn checkout or update cannot successfully get second sub-root
folder and files from svn server.

Let assume that we have on server one root folder and two sub-root folders.
In sub-roots folder have many files and directory.

User want to get all data from svn server to local directory "c:\ms_svn\"

Step to reproduce bug.
Start command

checkout "c:\ms_svn\" from htpp://server_svn.com/root/ --recursively

After starting command files start to downloading, but if network stop
after second file, second svn sub-root directory will never download on
user local machine.

root
    sub-root1
    sub-root2

We cannot start checkout "c:\ms_svn\" from htpp://server_svn.com/root/
--recursively because now have two files. If we start updata will will get
only files part of the sub-root1
