// kill parent. Should get "zombie!" equal to the number of zombies.
// ps or ^p should now show init as the parent of all child processes.
// init will then reap the zombies.
// 4. Can also be used to show that the RUNNABLE list is still round robin.

// --------------------------------------------------------------------------
// * All requests are absolute, i.e. all paths begin with / and
// include the complete path to a file or a directory. Symlinks,
// . and .. are already resolved.
// * For every request you can get except for getattr(), read() and
// write(), usually for every path argument (both source and
// destination for link and rename, but only the source for
// symlink), you will get a getattr() request just before the
// callback.
// For example, suppose I store file names of files in a filesystem
// also into a database. To keep data in sync, I would like, for
// each filesystem operation that succeeds, to check if the file
// exists on the database. I just do this in the getattr() call,
// since all other calls will be preceded by a getattr.
// * The arguments for every request are already verified as much as
// possible. This means that, for example
// * readdir() is only called with an existing directory name
// ...
// * read() and write() are only called if the file has been opened
// with the correct flags
// --------------------------------------------------------------------------
// Since this is run by a kernel module and can't just bail when there
// is a problem. Wrap errCatch (which has been made pthread-safe)
// around any calls to kent/src code.
