Sundials problem memory is not garbage collected

[ikirill]

Ideally, there should be a garbage-collected wrapper looking something like this:

type CVmem
  handle :: Ptr{Void}
  function CVmem(lmm::Cint, iter::Cint)
    mem = new(CVodeCreate(lmm, iter))
    mem.handle == C_NULL && error("CVodeCreate failed")
    finalizer(mem, CVodeFree)
    mem
  end
end

convert(::Type{Ptr{Void}}, mem::CVmem) = mem.handle

CVodeFree(mem::CVmem) = ccall((:CVodeFree, Sundials.libsundials_cvodes), Void, (Ptr{Ptr{Void}},), &mem)

Of course, the garbage collector won't always collect the memory aggressively if Sundials uses a lot of it, but it is much more "julia-like" to try to collect these pointers than to expect the user to call create/free pairs.

See #29. If you happen to have some time it would be great if you could take care of finishing #29. Shouldn't be much left to do ...

Maybe one should close this issue, since its all in #29?

The simplified interface now uses CVodeFree et al to free memory. The finializer idea is covered in #29.
