* - Continuous ringing of the bell is a nuisance.
* - Cannot allow access to the clipboard because a malicious script can
* replace the contents with the string "rm -r *" and lead to surprises
* when the contents of the clipboard are pasted. Similarly, the
* selection command is blocked.
* - Cannot allow send because it can be used to cause unsafe interpreters
* to execute commands. The tk command recreates the send command, so
* that too must be hidden.
* - Focus can be used to grab the focus away from another window, in
* effect stealing user input. Cannot allow that.
* NOTE: We currently do *not* hide focus as it would make it impossible
* to provide keyboard input to Tk in a safe interpreter.
* - Grab can be used to block the user from using any other apps on the
* screen.
* - Tkwait can block the containing process forever. Use bindings,
* fileevents and split the protocol into before-the-wait and
* after-the-wait parts. More work but necessary.
* - Wm is unsafe because (if toplevels are allowed, in the future) it can
* be used to remove decorations, move windows around, cover the entire
* screen etc etc.
*
* Current risks:
*
* - No CPU time limit, no memory allocation limits, no color limits.
* CPU time limits can be imposed by an unsafe master interpreter.
*
* The actual code called is the same as Tk_Init but Tcl_IsSafe() is
* checked at several places to differentiate the two initialisations.
