Modified: jk/native2/common jk_mutex.c jk_registry.c jk_registry.h
Added: jk/native2/common jk_mutex_proc.c jk_mutex_thread.c
Log:
A bit of refactoring. jk_mutex.c contains the common code for mutexes.
jk_mutex_proc is for inter-process locking, it won't work without APR.
jk_mutex_thread is for in-process locking.
Both objects can be used from Java ( via setAttribute/invoke() ). This
will allow java and apache to synchronize access to config files and
other resources ( the inter process locks ).
