Some of the tests are failing for unrelated reasons. I pushed a fix for those here #2007 |

We no longer block until the first insertion completes, and as such, we need to make sure that isEmpty correctly accounts for inflight inserts. This fixes a flaky test (only flaky for this branch) in the FeaturesVersionSupportTest.

We should probably improve test coverage on this patch, it seems that we have improved only one existing unit test

| { | ||
| if (timeoutMs-- <= 0) | ||
| throw new RuntimeException("Timeout while waiting for condition"); |

do we have unit tests that cover this condition ?
a RuntimeException will bubble up and hit any place in the code
would it be better to return false and handle the timeout explicitly ?

What is the issue

What does this PR fix and why was it fixed
This fix works in collaboration with datastax/jvector#521. Specifically, it focuses on removing the estimation aspect of the memory management and instead works by reserving more memory than is expected to be needed, then adjusting the real usage once the actual value of memory required is known. This should help reduce cases where we exceed the bytes used.
