* It also has two additional modes that are disabled and meant to be used by

|
|
* memory, it will be printed out as KERN_DEBUG in a format that can be passed
|
|
* to graphviz (the dot command) to visualize it. If you define the macro
|
|
* DEBUG_RANDOM_TRIE to be 1, then there will be an extremely costly set of
|
|
* randomized tests done against a trivial implementation, which may take
|
|
* upwards of a half-hour to complete. There's no set of users who should be
