Heschi Kreinick 61fa4dffed internal/memoize: fix race on read of handle.function
Late into CL 206879 I started nulling out a handle's function when the
handle finished running. That invalidated a previous assumption that the
field was immutable. Fix the assumption, and since the case of having
multiple computations in flight is at least a little bit possible, try
harder to avoid duplicate work.

Fixes golang/go#35995.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
