Thanks!
Could you try make test-all ? While some failures and errors are
expected, it stresses the interpreter a bit more, so it's a good way to
check that it doesn't block.

Err. This is fairly simple, and should not fail.
Could you try this version:
<---
a = []
trap(:INT) { puts "INT recvd" ; a.push(1) }
trap(:TERM) { puts "TERM recvd" ; a.push(2) }
pid = $$
puts "parent pid: #{pid}"
begin
fork do
puts "child pid: #{$$}"
sleep 0.5
Process.kill(:INT, pid)
Process.kill(:TERM, pid)
puts "signals sent."
end
sleep 1
a.sort
p a
rescue NotImplementedError
[1, 2]
end

Very strange. What about this script?
<------
m = Mutex.new
Thread.new { m.lock; sleep 3 ; puts "after m.lock in thread" }
sleep 1
m.lock
puts "after m.lock"
