Consider resetting thread usage when bytes object is cleaned

[alamar]

The following snippet is prevalent across our code:

    static class Notifier {
        Report er = new Report(Bytes.allocateElasticOnHeap());

        ... constructed in main thread, used in dedicated thread only...

    Report(Bytes bytes) {
        this.bytes = bytes;
        this.bytes.clearAndPad(256L);
    }

It will cause single thread checker warningd

On the other hand, binding bytes to thread is likely a heavy (and garbage-producing) operation, so it's possible that code which uses and cleans a small Bytes instance in a loop will become prohibitively slow if we simple clearUsedByThread() on every

Closing as it seems we are generally past this issue.
