This class has a limited subset of boost::thread's API. Construction is almost the same, but clients must supply a category and a name for each thread so that they can be identified in the debug web UI. Otherwise, <a class="el" href="classimpala_1_1Thread.html#a5fad57e14b212d8d1bc61b2c00948047">Join()</a> is the only supported method from boost::thread.

| <p>This constructor pattern mimics that in boost::thread. There is one constructor for each number of arguments that the thread function accepts. To extend the set of acceptable signatures, add another constructor with <class F, class A1.... class An>. In general:</p> |

| <li>category: string identifying the thread category to which this thread belongs, used for organising threads together on the debug UI.</li> |
| <li>name: name of this thread. Will be appended with "-<thread-id>" to ensure uniqueness.</li> |
