Reading a file can take a long time w/ prefetch enabled about soci-snapshotter HOT 1 CLOSED

Once the container is started, the prefetcher fetches spans in the background. It acquires the span's lock (in the span manager) and releases it once done. If an on-demand fetch comes in, the bg tasks are cancelled and restarted, but only after a 'silence period' of 5s. But the prefetcher is still holding onto the lock, which means on-demands fetches for those particular spans will have to wait 5+ seconds until the prefetcher releases the lock.

A short-term solution is to the silence period to 0s, which is what #105 is doing.

Longer term solution is to rewrite the prefetcher, which is being tracked in #106.

Closing this issue for now.
