That's true if looking at the raw line counts. It's not unexpected: 
Cancellation does allow some simplifications when there are more than one 
point, namely here vlc_tick_wait() and vlc_cond_wait().

Though some cancellation haters might counter that cancellation is 
intrinsically more complicated because of its abnormal call flow, and/or 
implementation cost (inside vlc_cond_t code).

I had no goal other than removing one case of CV cancellation.

 I suppose that it also provides a use case for vlc_sem_trywait(), which would 
only be for the same of API completeness.
