LoaderSymbol calls dlsym with RTLD_DEFAULT pseudo handle making it search in every loaded library. In addition glibc adds NODELETE flag to the library containing the symbol. It's used in doLoadModule to locate <modulename>ModuleData symbol, the module's library gets the flag and is kept in memory even after it is unloaded. This patch adds LoaderSymbolFromModule function that looks for symbol only in library specified by handle. That way the NODELETE flag isn't added. This glibc behavior doesn't seem to be documented, but even if other implementations differ, there is no reason to search ModuleData symbol outside the module's library.
