"DataObjects::Mysql::Command [...] in parallel should finish within 2 seconds" test failing on Debian FreeBSD/Hurd #33

Hi!

Datamapper tests are enabled when building datamapper-mysql packages for Debian. They pass perfectly, except on the Freebsd and Hurd architecture, when one test fails: The trace below is for Freebsd. The same test fails with Hurd (The number there is slightly above 4 seconds).

I see in the source that this particular test is marked as pending for Windows. Maybe it needs to be marked as pending for a larger class of OS containing also Freebsd and Hurd?

1) DataObjects::Mysql::Command it should behave like a Command with async running queries in parallel should finish within 2 seconds

This probably indicates that the underlying Ruby VM can't properly run multiple i/o requests in parallel. The problem is that I have no access to those platforms and can't really debug it because of that. A number of 4 seconds sounds like another issue though.
