> This task aims to fix the following miscellaneous issues of worst-case and
> parfor memory estimates:
> 1) Incorrect handling of incomplete worst-case estimates (can result in
> negative memory estimates)
> 2) Incorrect parfor estimates of operations with spark execution type
> (handled as forced execution type)
> 3) Incorrect parfor estimates in case of constrained optimizer with
> unspecified degree of parallelism and/or execution type.
