Add flag like '-xc' that only reports uncaught exceptions
The -xc RTS flag reports the stack trace of all exceptions. This can be very noisy when, for instance, certain http or parsing libraries are used that throw many exceptions, often handled fully internal, during their normal operation. Having multiple threads makes it even noisier. I'd think having a flag like -xc that only reports uncaught exceptions would be useful. It seems the GHCi debugger has a flag to only stop on uncaught exceptions, maybe this could be made available as an RTS option?
