Interesting suggestion, but I added the implementation with buffer = 1 here
and it still deadlocks:
https://github.com/egonk/chandemo/blob/master/2_3.go#L5
It stopped deadlocking when buffer = 5, so I think it will be a nice lesson

But it only happens when there are multiple cases where:

For example when there is only one case for "len(stem)

This has a good basis for a good discussion, whereas random thoughts often
don't. Also there's always room for a middle-ground.
Thinking aloud and random thoughts work somewhat in chats, but often
doesn't end-up in something tangible that can be used later on.

is to use special tokens and replace them afterwards...
Of course this approach has limitations in what it can do.
*// note: code untested and incomplete*
type Token string
type Queries struct {
pending sync.WaitGroup
means to create a new copy,

much nicer
and clearer. Lots of interfaces will disappear.
For storage.ID, it can be implemented as *interface{ Set(v string);
String() string }* or *struct { I uint64; B bson.ObjectId }* (with custom
marshalers)...

i.e. figure out what exactly you want to learn and use the best tool for

As a baseline measurement I suggest writing the same code in C; this shows
how much your VM / config / machine can handle.
With gopacket -- use src.NextPacket instead of Packets.
There are also: https://github.com/akrennmair/gopcap
and https://github.com/miekg/pcap

This doesn't sound like a real world problem, which means it's really
difficult to comment on the problem.
Currently the marshaling would work, but not unmarshaling.
Also, you can achieve the similar effect with:
