FYI: Multicore BatchJobs does not work on Solaris Unix (`ps -o ucomm` not supported)

[HenrikBengtsson]

Just an FYI, multicore BatchJobs does not work on Solaris because the linux-helper shell script uses command-line option -o ucomm when calling ps and this option is not supported on Solaris.

Below is the error reported by CRAN r-patched-solaris-x86 when future.BatchJobs (mine) runs tests relying on multicore BatchJobs tasks:

    Running the tests in ‘tests/BatchJobsFutureError.R’ failed.
