Andrew Gerrand a2a552218a godoc: rate limit file parsing on startup, improve diagnostics
When building the corpus of local packages, a "too many open files"
error would cause some directories inside GOPATH to be skipped.
Further, the error would not be reported because it was masked by a
"file not found" error from the GOROOT VFS layer.

This change adds a rate limit around parsing files when buildling
the directory tree, error reporting when godoc is run with -v, and
fixes the masked error issue in the vfs package.

It's possible that the rate limiting could be put into the
godoc/vfs/gatefs package, but I tried making the gate account for
open files (not just individual open/close/read/write operations)
but then godoc just hard locks (it wasn't designed to only open 20
files at once).

README

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 oracle 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.
