Ping. Now that there's some will to revisit bugs that have been long-ignored,
is anyone willing to look into and confirm the problem I've reported here? I
believe problem 2 is extremely serious and could lead to timing-based attacks
that corrupt memory and result in deadlocks or worse. Problem 1 is also serious
for long-lived processes with high reliability requirements that use thread
cancellation, as rare but undetectable resource leaks are nearly inevitable and
will accumulate over time.
