Vibe-d issue with timer in separate thread on debug builds

[Andres Clari via Digitalmars-d-learn]

Hi, I have an app that uses vibe tasks, fibers and timers 
extensively, and I found an issue only for debug builds, when 
canceling a timer. However the code in question works just fine 
in the release build.

But having this here makes testing certain things in my program a 
pain, since it'll crash on the assert in question:

vibe-d-0.8.2/vibe-d/core/vibe/core/drivers/libevent2.d:474
debug assert(m_ownerThread is () @trusted { return 
Thread.getThis(); } ());


Also, not sure I understand that assert properly... Is it 
checking the stop timer call is fired from the main thread the 
event loop is running? That would be bad, since basically that 
timer run from a child thread.
