No, it's not. =-)
APR_HAS_THREADS can be set to 1 and you can specify a prefork
(non-threaded) MPM. Most likely, that is what you are doing. This
actually incurrs a heavy performance penalty - APR must make itself
threadsafe when it doesn't have to. So, performance with prefork is
best if you say:
--with-mpm=prefork --disable-threads
apr_os_thread_current isn't defined if APR_HAS_THREADS is 0. Think of
FreeBSD. -- justin
