+Timeouts
+~~~~~~~~
+option:--blocking-timeout:
+ Set the channel's blocking timeout value to 'TIMEOUTUS' µs. 0
+ (default) does not block. -1 blocks forever until room is
+ available in the buffer to write the event. Positive
+ values are a timeout bounding the maximum blocking time
+ when trying to write into the buffer. Note that this option
+ only affects applications launched with the
+ LTTNG_UST_ALLOW_BLOCKING environment variable set.
