[ARC] Question on allocation handlings for seqs, string and refs

[cooldome]

Seqs and strings in arc mode are using sharedAlloc and deallocShared for memory management.

However refs are using:

when  defined(useMalloc):
    c_malloc(cuint s)    
elif compileOption("threads"):
    allocShared0(s)
else:
    alloc0(s)

I would like to aligns the approaches, but I am not sure if I would fix seqs/strings or refs.
Bare in mind that alloc, allocShared and c_malloc are the same thing under useMalloc, but are different otherwise.

Araq,
Please opine on what is the desired memory allocation approach and I will prepare a PR.

[Araq]

seqs/strings should follow ref's implementation strategy. Unless you can come up with good arguments for a different setup.

[cooldome]

Possibly, we can simplify it a little bit:

when compileOption("threads"):
    allocShared0(s)
else:
    alloc0(s)

When useMalloc is defined both allocShared and alloc means c_malloc already.
Does it sound good?

[Araq]

Yes.
