Works with network file systems. + threads2h.c Multi-Threaded/Multi-Process with latching implemented with test & set locks in the btree pages. + threads2i.c Multi-Threaded/Multi-Process with latching implemented with test & set locks in the btree pages with Linux futex system calls for contention.
