Hello, ok, I see the limitation and should be fixed in a way or another, even for 5.0. But maybe is better to use the system memory in this case, the shared memory requires locking and I don't see it's necessary in this case. Actually same happens with the mysql (or other db backends), they fetch the result in system memory and then our modules convert what's needed to pkg memory. db text has the lib embedded and that part can use system malloc. My suggestion is to define some aliases to memory functions, like dbt_malloc/dbt_free/..., pointing them to malloc/free/... or pkg_malloc/pkg_free/... based on a compile time flag and set it to the system malloc via module Makefile. Same is done by ctl module, which can be used as example, see: src/modules/ctl/ctl.h .
