Most tests already had no global state, however parallel was never enabled. This change enables it for all applicable tests.

This makes it possible to optionally omit the identifying verbose message, for when the Op implementation can provide a much more useful message in its case, using information not yet available to the String method.

This synchronises the wait4 return after the toplevel signal call in lowlastcap_signaled_cancel_forward_error.

These are very useful in many packages containing relatively large amount of code making calls to difficult or impossible to stub functions.

This helps indicate the exact origin and nature of the error. This eliminates generic WrapErr from container.

The mount function now wraps its own errors in a much more descriptive type with proper message formatting. Wrapping them no longer makes any sense.

This used to be entirely done via integration tests, with almost no hope of error injection and coverage profile. These tests significantly increase confidence of future work in this area.

This is simultaneously more efficient and less error-prone. This change caused minor API changes in multiple other packages.

This is way higher level than the container package and does not even work unless every path is mounted in the exact same location.
This behaviour causes nothing but confusion and problems,

This is more elegant and allows for much easier extension of the tests. Mountinfo is still serialised however due to libPaths nondeterminism.
