Commits on Aug 8, 2022

  1. Add ability to specify maximum memory a pony program is allowed to use 

    Prior to this commit, a pony program would keep growing in terms of
memory use until the OS would be unable to allocate more virtual
memory.

This commit adds a new `--ponymaxmem` command line argument to limit
the maximum amount of dynamically allocated memory a pony program is
allowed to use before the runtime refuses to allocate any more. The
limit enforced is in MB and does not exactly match the RSS of a
process in linux due to memory allocated by the process outside of
the pony pool allocator.

  2. Add aggressive gc threshold and factor functionality 

    This commit adds two new command line arguments to allow for
enabling aggressive GC when the program is using more than a set
threshold of memory. The new command line options are
`--ponyaggressivegcthreshold` and `--ponyaggressivegcfactor`.

  3. Add ability to send arrays in pings to message-ubench 

    This commit enhances the message-ubench example application to be
able to send arrays of arbitrary sizes as part of pings from one
actor to another. It also includes the ability to specify how long
a receiving actor should hold on to arrays before freeing them for
GC.
