the capacity of the channel corresponds to the maximum number of simultaneous uses,
sending an item acquires the semaphore, and receiving an item releases
the semaphore.
This is a common idiom for limiting concurrency.

<p>
This program starts a goroutine for every entry in the work list, but the
goroutines coordinate using the <code>limit</code> channel to ensure

  owners should update their assembly code to avoid the alignment assumption, as this
  workaround will be removed in a future release.

  On the <code>windows/amd64 port</code>, programs linking or loading Go libraries built with
  <code>-buildmode=c-archive</code> or <code>-buildmode=c-shared</code> can now use
  the <code>SetUnhandledExceptionFilter</code> Win32 function to catch exceptions not handled

Go programs are constructed by linking together <i>packages</i>.
A package in turn is constructed from one or more source files

The <code>FUNCDATA</code> and <code>PCDATA</code> directives contain information
for use by the garbage collector; they are introduced by the compiler.

To see what gets put in the binary after linking, use <code>go tool objdump</code>:
