I guess it's reasonable to argue that this isn't a source compat break 
because it's not the default build configuration; the config option used 
to enable it needs to make that pretty clear in that case.  It still 
sounds like a bit of headache.  Do you think it's really so important to 
do get this changed now in 1.x?

I'm not sure what you're asking here.  Starting in 1.3.x there can be 
multiple global pools each under control of separate consumers.

Right, exactly.  And in 1.3.x X and Y might be passing their own 
independent global pool to apr_ldap_init() or whatever - snafu ensues.
