Re: [389-devel] Please review ticket 47936: Create a global lock to serialize write operations over several backends

[Ludwig Krispenz]

Hi,

does it make sense to allow subsets of the backends to be locked by the 
global lock. In our experience with deadlaocks different combinations of 
backends were involved - so to enable it one would have to know in 
advance which backends to list. I think if we introduce this global 
lock, make it global, it would also make the config check if it should 
be used faster.

If you want to keep the configuration of individual backends I would 
like to have one "ALL" option
