Abstract:
1. A method of squeezing slabs empty, a slab being a block of allocated memory space, the method comprising the steps of: determining whether a slab is to be squeezed empty, a collection of slabs being a pile, each pile having a maximum amount of allowable space that can be allocated thereto, wherein if an application reduces the maximum amount of allowable memory space of a pile and the current amount of memory space exceeds the reduced maximum, at least one of the slabs in the pile is targeted to be squeezed empty; precluding, if the slab is to be squeezed empty, data from being placed in any unused space of the slab and in any space in the slab that becomes unused anytime thereafter, wherein precluding data from being placed in an unused space of the slab includes disclaiming the unused space; and de-allocating the slab when the slab becomes empty.
