Oh, this is interesting: tclInterp.c's SlaveCreate() has a special purpose hack now: /* * The [clock] command presents a safe API, but uses unsafe features in * its implementation. This means it has to be implemented in safe interps * as an alias to a version in the (trusted) master. */ if (safe) { Tcl_Obj *clockObj; int status; TclNewLiteralStringObj(clockObj, "clock"); Tcl_IncrRefCount(clockObj); status = AliasCreate(interp, slaveInterp, masterInterp, clockObj, clockObj, 0, NULL); Tcl_DecrRefCount(clockObj); if (status != TCL_OK) { goto error2; } } So apparently it's still *supposed* to work, but there's something about the way we are using tcl that makes it not work.
