bulkmail_increment_threadcount

bulkmail_increment_threadcount

Increment the number of in-use threads. This is actually a different variable than the completed threads variable, so that we won't block.

Source code:

    
    ns_share bulkmail_threads_spawned_mutex
    ns_share bulkmail_threads_spawned

    ns_mutex lock $bulkmail_threads_spawned_mutex
    catch {
	incr bulkmail_threads_spawned
    }
    ns_mutex unlock $bulkmail_threads_spawned_mutex
