| | | | | | | | | | | | | | | | for building program and rpc headers. - clustering translators like replicate assume iobrefs will be used as read-only by lower layers and there by use the same iobref while winding calls to multiple children. Since iobrefs can hold only limited number of iobufs, this limits the number of children these translators can have without overflowing iobrefs.

Switch over fcntl lock based pidfile handling which can provide reliable info about status of the process.
