ra_svn tests stuck in diff_tests.py

Two times today while trying to run through the svn_ra tests (make
svncheck) the processes have hung. After the first time, I ran it again and
it worked.

The second time it hung I looked with gdb to see where it was hung.
There were several svnserve processes active. Here is a backtrace of one
svnserve:
#0 0x420e8132 in accept () from /lib/i686/libc.so.6
#1 0x401db593 in accept () from /lib/i686/libpthread.so.0

Does any of that help determine why it hung? It seems to be sporadic,
sometimes it hangs and sometimes it doesn't.

This is Subversion 0.17.0-4468 on RedHat 7.3, all latest patches applied.

  Thanks!
