My initial mail in this sub-thread listed the pure minimum of things to solve. dl() is useless if PHP crashes on following requests as an extension didn't clean up while unloading or loading fails as the operating system didn't clean up fully. Yes, dl() right now won't directly break with some extensions on some operating systems ... but there are too many fragile pieces for serious production use - that's why we limited dl(). If there is somebody with knowledge about runtime linking, loading and unloading they are very welcome to see how to make it stable and where to limit PHP internal API. I'd love to get rid of global pecl installs but its unfortunately not a "minor technical detail"... hrm thinking about deployments etc. I think it is even more complicated as we'd have to define a clean stable API else upgrading etc becomes a mess ... johannes
