Actually it's really not the fact that callback are 
synchronous that bothers me.

For instance, assume we have library A that uses libxml2, 
and library B that uses libxml2 too.
Both need to catch global error messages, but they don't
know about each other. They can't both register their own
global xmlGenericError at the same time, right?

The last error mechanism is only a proposal to work 
around this without requiring far reaching changes to 
the APIs.
