Memory Allocation. Suppose there are two operations: request (amount) and release(amount),

Memory Allocation. Suppose there are two operations: request (amount) and release(amount), where amount is a positive integer. When a process calls request, it delays until at least amount free pages of memory are available. A process returns amount pages to the free pool by calling release. Pages may be released in different quantities than they are acquired. (a) Develop a monitor that implements request and release. First specify a global invariant. Do not worry about the order in which requests are serviced. Use the Signal and Continue discipline. (Hint: Use a covering condition.)
