Fix linking problem when enabling thread safety on Darwin: uninitialized
global variables are problematic on this platform. Simplest solutionseems to be to initialize pthread key variable to 0. Also, rename thisvariable and check_sigpipe_handler to something involving "pq" toavoid gratuitous pollution of application namespace.
