 There are three major code sets in the btree source code:
 
 btree2q.c       Single Threaded/MultiProcess with latching supplied by advisory file locking.  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.
+
 The Foster set includes three types of latching:
 
 Fosterbtreee.c  Multi-Threaded/Single Process with latches hosted by the buffer pool manager
+
 Fosterbtreef.c  Multi-Threaded/Multi-Process with latches hosted by a latch manager using the first few pages of the btree.
+
 Fosterbtreeg.c  Multi-Threaded/Multi-Process with latches implemented with test & set locks in the btree pages.
 
+
 Compilation is achieved on linux or Windows by:
 
 gcc -D STANDALONE threads2h.c -lpthread
