Options:

• :pool-size The number of connections to keep open. Default 4.
• :reconnect-interval How many seconds to wait between attempts to connect. Default 5.
• :claim-timeout How many seconds to wait for a Logentries connection from the pool. Default 0.1.
• :block-start Wait for the pool’s initial connections to open before returning.
