Sounds like a bug in svnserve. Once it detects that its input is at EOF, it
should terminate. I'd suggest that you 'gdb svnserve' and then at the gdb
prompt 'attach' to one of the hanging svnserves. Then you can at least get a
backtrace so developers can tell where it is hanging.
Also, I believe that xinetd can log the PIDs of started servers, thus you
might be able to make out which operation was performed and from where.
