[PATCH] small fix for memory leak in svn_wc_props_modified_p

From: Joel Rosdahl <joel_at_rosdahl.net>

Good evening.

I have done some experiments to see how good Subversion currently is
at handling lots of source code. More specifically, I tested to
import/checkout/status/update/commit the Linux 2.2.21 code using a
crude benchmark script. Current time results at my system:

  Import: 358.3 s
Checkout: 348.4 s
  Status: failed
  Update: 21.9 s
  Commit: 60.4 s

(This is for ra_local.)

I won't comment the numbers, but rather the memory usage; it goes up
to at most 50 MB for import/checkout/update/commit, but running "svn
status" makes svn eat insane amounts of memory, and it consequently
gets killed for its greediness. :-) I think the attached patch fixes
the problem.

* subversion/libsvn_wc/props.c (svn_wc_props_modified_p): Avoid memory
  leak by passing subpool to svn_wc_entry.
