Hi,
The original bug appears to still be there. For example this will hang:
(defun test () (let ((object (cons nil nil))) (threads:synchronized-on object (threads:object-wait object 0.000000001))))

Sigh. Yes, this is still not resolved with THREADS:OBJECT-WAIT in abcl-1.4.0-dev, although CL:SLEEP is fixed. Apparently my thinking on this was incomplete. For the SLEEP, degrading to thread yield make sense for intervals less than a nanosecond. For OBJECT-WAIT is it really the case that you wish to degrade to a thread yield without ever having tried to wait for a notification on the synchronized object? -- "A screaming comes across the sky. It has happened before, but there is nothing to compare to it now."
