Goal of these two programs is to allocate memory and free it in various ways. C is obviously much simpler than Go, and C version is making some rough attempt to allocate and de-allocate in a similar way to the go runtime.
cd c_version
gcc -o cmadv main.c
./cmadv
cd go_version
go build -o gomadv
./gomadv
To "view the results" the idea is to check the OS level RSS reported.
hwatch 'ps e -o "rss,vsz,pid" -p $(pidof gomadv)'
In the C version, this appears to be pretty immediate and correctly reduces the RSS.
In the Go version, the RSS goes down immediately post FreeOsMemory.
It seems to take ~1min for the scavenger to return the memory otherwise.
