Fair enough. It's just that the code to reproduce the problem is so
simple, it seems that someone else may have hit it. My real code
to load up subversion is a little more involved of course. But it
still sets up no callbacks for logging, going through checkin results, etc.

The code below will show one connection after the checkout, and 2
after the checkin. Anything talking to the repository will add another
connection (until I'm out of descriptors).


use SVN::Core;
use SVN::Client;

*WORKDIR = \"/some/work/dir";
*REPO = \"svn://somehost/somerepo";

# callback for authentication
sub simple_prompt {
  my ($cred,$realm,$default_username,$may_save,$pool) = @_;

$mypid = $$;
my $ctx = new SVN::Client(auth =>
$ctx->checkout($REPO, $WORKDIR, "HEAD", 1);
print "Done with checkout, connections:\n";
system("lsof -p $mypid | grep TCP");
`echo blah > test.txt`;
$ctx->commit("test.txt", 0);
print "Done with commit, connections:\n";
system("lsof -p $mypid | grep TCP");
print "Done.\n";
