Returning memory to the OS during runtime is very rare among UNIX programs in general. I would support the creation of some function (perhaps in the sys module) that would cause Python to do this (perhaps sys.free()? or sys.sbrk(-1) or something like that).

However, the saner answer for a daemon process that's about to generate a 250MB report (or otherwise use a tremendous amount of memory) would be to fork(), generate the report, and exit(). The memory allocations will all happen in the child and it's memory will be freed back to the OS when the child process dies.
