Source sets are a powerful concept that tie together several aspects of compilation:

 * the source files and where they're located

  // A note on memory visibility.
  // Many of the utilities in this class (transform, withFallback, withTimeout, asList, combine)

  // 1. Cancellation should propagate from the returned future to the input future(s).
  // 2. The returned futures shouldn't unnecessarily 'pin' their inputs after completion.

identifiers not by parsing C code but by feeding carefully constructed
programs into the system C compiler and interpreting the generated
error messages, debug information, and object files. In practice,
parsing these is significantly less work and more robust than parsing
C source.

Cgo first invokes gcc -E -dM on the preamble, in order to find out
about simple #defines for constants and the like. These are recorded
for later use.

Because metadata verification can significantly increase the size of your configuration file, you may therefore want to disable verification of metadata.
If you understand the risks of doing so, set the `<verify-metadata>` flag to `false` in the configuration file:

	// precomputing some number of those and cache for future reuse.
	precomputedProbabilities []string

	// The following buffers are used to reuse memory and avoid allocations
	// that are significantly impacting performance.
	iptablesData             *bytes.Buffer
	existingFilterChainsData *bytes.Buffer
	filterChains             proxyutil.LineBuffer
