That "wait for something else" normally refers to <abbr title="Input and Output">I/O</abbr> operations that are relatively "slow" (compared to the speed of the processor and the RAM memory), like waiting for:

* the data from the client to be sent through the network
* the data sent by your program to be received by the client through the network

Other memory operations are <i>write-like</i>, including write, atomic write, mutex unlock, channel send, and channel close.
Some, such as atomic compare-and-swap, are both read-like and write-like.

A <i>goroutine execution</i> is modeled as a set of memory operations executed by a single goroutine.

// Note: There are two changes in the expression handling here

//
// 1) Evaluation uses uint64; the old one used int64.
