We have a few memory leaks in tlclient. We should try to fix these.
==17986== LEAK SUMMARY:
==17986== definitely lost: 1,332 bytes in 18 blocks.
==17986== indirectly lost: 23,645 bytes in 100 blocks.
==17986== possibly lost: 8,685 bytes in 1 blocks.
==17986== still reachable: 105,107 bytes in 529 blocks.
==17986== suppressed: 0 bytes in 0 blocks.
Fixed most of these. What remains is a strdup() for putenv() (don't think we can get rid of that one), and a few leaks in FLTK for its font handling.
