External constaints have forced our processing to be divided
between two processes. The relationship is strictly
a client - server one, process A wants a service from
process B and can do no useful work until it completes. Is
there any method of interprocess communication (mailboxes,
event flags, locks, etc) which will minimize the cost of the
context switch between the two processes (assuming that any
actual data is transferred via shared memory).
Thanks in advance.
