[vwnc] DLLCC, _threaded and mac

Matthias Junker
Hi,
i'm building dllcc bindings for the subversion client. However because  
i had problems with system interrupts, i tried to make the calls to  
the C client _threaded. Under linux, this works fine, but under mac,  
visualworks just freezes and nothing happens. Did anyone have similar  
experience with _threaded under mac? I'm glad for any kind of feedback.

Cheers
Matt

On Leopard? I've experienced similar deadlocks with the THAPI on Leopard
(Intel) and/or PPC machines and discussed this on vw-dev recently. The
solution proposed by Eliot did it, but it'll need to be applied to the
VM. IIRC, it was because Apple changed something with the kernel (time
struct).
