The semantics of this change are that the last line will be subsituted
in place of the expression, where as the lines before that will undergo
variable substitution and be prepended before the lowest (in the AST
tree sense) statement which included the expression.

Previously we would spin up a new goroutine for every directory
we needed to parse. Since parent directories cannot exit until
children have exited, in large GOPATH directories we could have 8000+
goroutines evaluating directories concurrently. The race detector uses
tsan, and tsan can handle a maximum of 8192 concurrent threads at one
time.
Limit the number of concurrent threads. It is difficult to do this
in a way that does not involve a child being blocked on a parent
completing to spin up goroutines for itself to complete. Solve this by
completing work on the main thread if there are no additional workers
available to help complete work.
I was expecting limiting the concurrency to hurt performance, but it
actually significantly improves it. Benchmarks were performed using CL
94904 at tip, and with goroutines at 2, 4, and 8 times the number of
CPU's.

This regression is due to https://go-review.googlesource.com/c/go/+/100235
which made the go/scanner behavior match the compiler's scanner by
not modifying filenames in line directives in any form. Specifically,
relative filenames now remain relative. This makes it easier to reason
about the behavior of the scanner but may require clients to adjust
those filenames.
If removing the longer path in the .golden file is not satisfactory,
the (scanner) client may have to massage positions returned via line
directives; or better, the line directives are created with extended
path information.

We used a css-pseudo class rule to move the line number inside
the pseudo element. The idea was to prevent line numbers from getting
selected while copying the code. But this was already implemented
with the "user-select: none" rule.
Since the spec was undefined on "user-select", we had to resort
to the pseudo-class, but now both FF and Chrome implement the correct
behavior.
Hence, moving the content to be inside the span, and removing the
pseudo-class rule.
Manually tested with Chrome 63 and Firefox 58 on Ubuntu.

if the user workspace is significantly large and the files

This CL spawns off the initialization in a separate goroutine

The http handler checks the flag and returns an error response

The check is only performed for the path prefixes handled by the
