ulimits for `lilypond-test' in gub

[Werner LEMBERG]

Folks,


running `lilypond-test' in gub uses the following ulimit values for
creating the regression EPS files:

  ulimit -m 524288
  ulimit -d 524288
  ulimit -v 2097152

Interestingly, this is not sufficient on my 64bit openSuSE 42.3
GNU/Linux box with my forthcoming changes to restrict fontconfig to
fonts from gub only: Handling the file name list file
`out/lybook-testdb/snippet-names-5692165138572845334.ly' fails in
job 1 while processing file `40/lily-dee14dc0.ly' (i.e.,
`paper-twosided.ly')

Generously increasing ulimit parameters

  ulimit -m 1048576
  ulimit -d 1048576
  ulimit -v 3145728

did work, however.  How shall I proceed?  Is there an easy way to find
the minimum ulimit values that are necessary and/or sufficient?  I can
imagine this influences the settings needed for creating and running
VMs...

Attached is a script that exactly replicates the problematic lilypond
command (with all the necessary environment variables) in case people
want to play with it.
