Hi, it's great to see another person having a go at Kobo dev.

If the library segfaults, generally the Kobo will reboot.
NickelHook has protections included to prevent boot loops. If the Kobo reboots before a timeout is reached, the library will not be loaded for the next boot. Even if a boot loop happens, it is still possible to reset the Kobo using the official recovery script. Unless you are messing with the Bootloader, Kernel or init scripts, it is almost impossible to brick a Kobo.
Telnet or SSH access is highly recommended. NickelHook provides functions to log to syslog, which you can read using logread. It is also possible to log to a file somewhere in /mnt/onboard as well.

Note the above is for devices running firmware 4.x ONLY.

EDIT: I see you have a Clara BW, this should be ok to work with, but you might want to check with others running the newest devices to make sure there are no gotchas to be worried about.

Have fun!
