I can't explain this one.

I *might* be able to explain at least a portion of this one.

My code calls the (new) get_wc_contents RA callback to get a read stream for
the pristine text matching the specified SHA1. This will open the pristine
file. The file remains open until its contents are consumed (whenever
Serf/ra_serf get around to doing so per the pipelined approach taken to
GET/HEAD/PROPFINDs during updates). I suppose if the code which is cramming
pipelined requests (the result of parsing the initial REPORT) into the queue
outpaces the code that's handling those requests, you could wind up with too
many open files.
