We use thread-local-storage quite a bit in Asterisk, but we (for the reasons you mention) don't use GCC's version of it, we use the direct pthread library calls for allocating and freeing TLS keys. These keys have destructor callbacks, so we have complete control over the TLS object lifetimes. -- Kevin P.
