I just rebuilt my system to see if the problem had perhaps been solved, but it's still doing it. It doesn't cause any problems (the process doesn't look like it's doing anything, just not going away) so I am gonna just let the processes sit there. root@basement:/usr/src/tools/KSE/ksetest# ./ksetest main() : 0x804c000 eip -> 0x280c06b3 uts() at : 0x8048e20 uts stack at : 0x814d000 - 0x8155000 main() : 0x804c400 eip -> 0x280c06b3 uts() at : 0x8048e20 uts stack at : 0x8255000 - 0x825d000 thread_start() : 0x804c800 804c800 thread_start() : 0x826d000 826d000 kse_create() -> 0 +-kse_create() -> -1 main() : 0x826d800 eip -> 0x280c06b3 uts() at : 0x8048e20 uts stack at : 0x837e000 - 0x8386000 main() : 0x826dc00 eip -> 0x280c06b3 uts() at : 0x8048e20 uts stack at : 0x8486000 - 0x848e000 thread_start() : 0x848e000 848e000 thread_start() : 0x848e800 848e800 thread_start() : 0x84af000 84af000 kse_create() -> 0 A*.kse_create() -> -1 [...] *R*.S.*T*.^C^D^Z (no response on this tty, so I close it).
