 /*
  * When an interpreter trace is active (i.e. its associated procedure is
  * executing), one of the following structures is linked into a list
  * associated with the interpreter. The information in the structure is needed
  * in order for Tcl to behave reasonably if traces are deleted while traces
  * are active.

 				 * procedure returns; if this trace gets
