I am at a bit of a loss.  Something appears to be deleting files from
underneath Subversion.  The file that goes missing while processing the
DELETE request was almost certainly present when we started processing
the DELETE, since readdir() returned its name, but a very short time
later was not present.  The code that implements DELETE is relatively
simple and in the log you gave it is not even running in the same
process that processed the MERGE.  It could be a Subversion bug but I
struggle to see what sort of bug would lead to this effect.
