Replace intrcheck() by sigcheck() in many places. In Pythonrun, tirn off SIGPIPE and move signal handlers elsewhere. In ceval.c, also move locals_2_fast/ fast_2_locals to frameobject.c, replaced local variable trace by f->f_trace, got rid of unused mergelocals() and unneeded calls to fast_2_locals, return the variable name on "fast variable not found", AND use "__call__" method if it exists to call an inmstance. Whew!
