-- The primary freedom of open source is not the freedom from cost, but the free- dom to shape software to do what you want. This freedom is /never/ exercised without cost, but is available /at all/ only by accepting the very different costs associated with open source, costs not in money, but in time and effort. -- http://www.schierer.org/~luke/log/20070710-1129/on-forks-and-forking --Boundary-00=_O6HKHoQQJlEsW1J Content-Type: application/octet-stream; name="bt_full" Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="bt_full" Thread 5 (Thread 1082132832 (LWP 10915)): #0 0x00002b5a2fb75eeb in __lll_mutex_lock_wait () from /lib/libpthread.so.0 No symbol table info available. #1 0x00000000407fc9c0 in ??
