+	Improved valgrind support.
+	* configure.in: Remove all remnants of the purify support, since
+	it was broken when we switched to automake.  Added valgrind
+	support.
+	* src/server/testsuite/.cvsignore: Ignore valgrind-*.log.
+	* src/server/testsuite/Makefile.am (site.exp): Set valgrind.
+	* src/server/testsuite/config/unix.exp: Use the "valgrind"
+	variable from site.exp.  It contains a the path name of the
+	valgrind binary to use.
+	(spawn_lyskomd): Adjust accordingly.  Don't use -v.
+	(check_valgrind): New argument: expected_leaks.
+	(lyskomd_death): Pass the new optional argument "expected_leaks"
+	to check_valgrind.
+
+	Note a memory leak.
+	* src/server/testsuite/lyskomd.0/regexp-match-cov.exp: Bug 689 is
+	a hard-to-fix memory leak.  Mark it as an expected failure.
+	(shutdown): Pass info about expected leaks to lyskomd_death.
+
+	Shut up valgrind.
+	* src/server/memory.c (init_person): Clear the pwd field.  This
+	way, we avoid writing junk to the database file, and we make
+	valgrind happy.  The junk was never used, so this is not a
+	bugfix.
+
+	Test suite fix.
+	* src/server/testsuite/lyskomd.0/27.exp: Use idholl where
+	appropriate.
+
 	Fix a minor memory leak.
 	* src/server/aux-items.c (free_aux_item_definitions): Fixed a
 	memory leak.  We have to call regfree() to deallocate stuff within
