[issue33065] IDLE debugger: failure stepping through module loading

[ppperry]

ppperry <mapreader at olum.org> added the comment:

Line 59 isn't actually executed; the error comes from the trace event that gets fired before line 59, which is the first `line` event in the frame containing the uninitialized _ModuleLock.
