Detailed Description

Asynchronous events are used for events that are not scoped to a single thread and have duration. They have an additional 'id' argument which is used to match up the START and END events.

Example:

// Thread 1
TRACE_ASYNC_START0('Memcached:Frontend', 'EWOULDBLOCK', 123)

// Thread 2
TRACE_ASYNC_END0('Memcached:Frontend', 'EWOULDBLOCK', 123)
