eldritch horrors
e47bff547a
4138fc7622 mistakenly removed an early
exit from non-main worker threads. this led to exceptions not ending
`process()` calls in a timely manner and instead draining the entire
work queue first, which for e.g. Interrupted errors would cause many
duplicated reports per worker thread instead of only one per thread.
it also did not properly rethrow a work item exception in all cases,
e.g. when all work had completed by the time `process()` was called.
due to a mistake in the thread starting check it was possible that a
system would require n² work items to start n worker threads if some
work items process quickly enough while other items block for a bit.

# NOTE(Qyriad): This file is one big slab of boilerplate.
|
|
# Lix's current unit test organization is scattered and entagled.
|
|
# Each of the test-support libraries could theoretically be a somewhat self-contained
|
|
# subdir(), but literally nothing else can. Each of the tests have dependencies on other
|
|
# test support libraries, and so do their support libraries.
|
|
# Each of the tests have dependencies on their own andother test support libraries,
|
|
# and so do their support libraries, and they have entangled dependencies on Lix's mainline
|
|
# lib* targets as well.
|
|
# The only boilerplate reduction I really could do here is throw everything in big nested dictionaries
|
|
# and dynamically generate and refer to targets based on abstracted specs, but without user-defined
|
|
# functions, the result would be way less readable than just a bit of copypasta.
|
|
# It's only ~200 lines; better to just refactor the tests themselves which we'll want to do anyway.
