We believe the disk writes are caused by fcntl(). Its updates to the

fcntl(F_RDLCK) and fcntl(F_UNLCK) should be adjusting some data
structures inside the kernel only. Those calls should *never*
modify the disk. What OS are you running?
Also, we can't understand why each select statement has access() and
fstat64() calls for each select.
These are to check to see if another process has modified the database
since you last read it. They also check to see if another process
was in the middle of modifying the database but crashed and thus the
partially completed changes need to be rolled back.
