Using a trunk client with ra_serf checkout ^/subversion/branches/1.7.x and then
switch to ^/subversion/branches/1.8.x. On my system with ulimit -n set to 1024
the switch fails:

svn: E000024: Can't create temporary file from template
'/home/pm/sw/subversion/src-1.8/.svn/tmp/svn-XXXXXX': Too many open files
Looking at /proc/NNN/fd I see that the program has 558 open files in .svn/tmp
and 455 open files in .svn/pristine.
The same switch is perfectly OK with 1.7/neon.
