Whether the parallel tool has the similar size limit problem as xargs?

[Hongyi Zhao]

As far as the following command is concerned:

$ find ./source -type f | xargs sort -o bbb -u

Lew Pitcher told me that it has the following limitation [1]:

The above command depends on xargs(1) to provide sort(1) with a list
of input files. As the size of this list depends on both the number of
files found, /and/ the maximum size of an argument vector (argv[]), there
is a chance that the file bbb will only contain the sorted contents of
a subset of the files found by find(1).

So, I want to know whether the parallel tool still has the similar problem.
