Re: X error handler

[Richard Stallman]

    It seems to me cleaner to make the protocol error handler do nothing
    by default (rather than kill Emacs).  When x_catch_errors is on, we
    can carry out the current behavior, i.e., storing the error string
    etc.

This might be a good idea, but I tend to think there must have been
some reason for writing the code originally not to do so.

Can anyone think of a drawback for this?

One possible drawback is that bugs get ignored rather than fixed.
But I am not sure that really matters.
