852523 - setting IONFLAGS to an invalid value is treated as 'all'

Status: RESOLVED INVALID

(Core :: JavaScript Engine, defect)

I accidentally set IONFLAGS=aborts instead of IONFLAGS=abort, and the result was that it ended up treated as IONFLAGS=all, and js shell spent 10 minutes chugging and generating ~2gb of control flow graph and json data before I killed it.

Not the worst thing in the world, but I'd suggest that an unrecognized value should either always produce the equivalent of IONFLAGS=help, or unrecognized values should be ignored and if the only values in IONFLAGS are unrecognized, it's treated as if you didn't set it at all.

Actually, now I'm confused. The source code says the channel is named 'abort' but IONFLAGS=help says it's named 'aborts'. I will have to figure out what actually happened here. :/ Probably invalid.
