[pacman-dev] Non-reentrancy of libalpm, why?

Hi, I noticed that libalpm isn't reentrant/thread-safe, even though it defines pmhandle_t to store all global information instead of using multiple global variables. This is unfortunate for my use case. I'm thinking about writing a cross-compiling makepkg-like utility, which would need to access two package handles simultaneously at once: that of the host and that of the target. Is there a reason why libalpm isn't reentrant? And how frozen is the libalpm API supposed to be? Thanks, Patrick
