The documentation of the synapser build system refers to "slaves" that test the package on different platforms. Can we please consider using a different word that is more culturally sensitive to refer to these machines?
I am aware that "master/slave" has a history as standard terminology in the computing industry, but I don't think that's a good reason to keep using these terms. Many other projects (Django, Drupal, etc.) have also abandoned this terminology.
"Worker", "replica", or simply "machine" all seem like reasonable replacements.
