Hi Sabu,
Memory is auto-recycled.
You can force recycling with the recycle function.
You can test the memory allocated by your program with system/stats
You can have an idea of memory used by some code with these routines:

> cfg: make object! [] ; global variable. Is this needed?
No.
> pp: [] ; global variable. Is this needed?
No. Non locals are made globals in Rebol when you load a file.

You should use load/all.
To-block works, but it does not load words in the global context.
Un-loaded words are buggy in Rebol and can lead to crashes.

your function can become:
loadCfg: func [cfgfile][
not error? try [
cfg: make object! load/all cfgfile
]
]
>> loadcfg "a: 2"
== true
>> probe cfg
make object! [
a: 2
]
You should know that make object! executes the body block (the loaded block),
so it is not secure.
