shm-signal: shared-memory signals
shm-signal provides a generic shared-memory based bidirectional
signaling mechanism. It is used in conjunction with an existing
signal transport (such as posix-signals, interrupts, pipes, etc) to
increase the efficiency of the transport since the state information
is directly accessible to both sides of the link. The shared-memory
design provides very cheap access to features such as event-masking
and spurious delivery mititgation, and is useful implementing higher
level shared-memory constructs such as rings.
We will use this mechanism as the basis for a shared-memory interface
later in the series.
