What kind of troubles?  I'm not really sure what this flag is used
for, so I can't say whether it's safe to remove.  It doesn't seem that
we use it for much, and the places that do use it are not very clear
about its purpose.

In principle I wouldn't mind removing it, but I would like to
understand why exactly.

Jan, any insights?


Thanks.  Diego.
