The threads correctly release the cached structures on subsequent calls. Memory is reclaimed when threads exit by a destructor routine. For those with an interest in seeing the implementation, see the lu_utils.[ch] files and any one of the lu_*.c routines (e.g. lu_host.c) in the Libinfo project: http://www.opensource.apple.com/darwinsource/ 10.4.6.ppc/Libinfo-222.1/lookup.subproj/lu_host.c This email sent to site_archiver@lists.apple.com
