[vtkusers] Mutexlock::Trylock?

[Sebastien Valette]

Hi,

I am experimenting multithreaded computing, and I face a performance 
issue due to my locking scheme. In this context, I think a method such 
as vtkMutexLock::Trylock() would solve (at least partially) my problem. 
Basically, trylock tries to acquire one lock and returns a value 
depending on the success of the lock acquisition (without blocking the 
thread). This method does not exist in the vtkMutexLock class.

Does anyone know what is the most easy thing to do if I want such a 
feature? Is an extension of the vtkMutexLock class possible?

Sincerely,

Sebastien
