Calling runtime.Stack requires the buffer to be big enough to fit the
goroutines dump. If it's not big enough the dump will be truncated and
the value returned will be the same size as the buffer.
The code was changed to handle this situation and try again with a
bigger buffer. Each time the dump doesn't fit in the buffer its size is
doubled.

Add handler for SIGUSR1 based on feedback regarding when to dump
goroutine stacks. This will also dump goroutine stack traces on SIGQUIT
followed by a hard-exit from the daemon.
