[Pharo-dev] atomicity of non-local returns

I understand generally that an inlined #ifTrue is atomic. For example, here after the primitive returns, no interruption can occur before the #ensure is invoked... self primitiveWaitAcquire ifTrue: [mutuallyExclusiveBlock ensure: [self release]]. But I want to know whether a non-local return could have an impact on that atomicity. For example ... self primitiveWaitAcquire ifTrue: [ ^ mutuallyExclusiveBlock ensure: [self release]] cheers -ben
