[Rake-devel] 'thread tried to join itself'

[Ittay Dror]

Hi,

After building ruby with --disable-pthreads (which still leaves it 
linked to libpthread)  I started getting a 'thread tried to join itself' 
errors on the line '@lock.synchronize' in invoke_with_call_chain. After 
switching from Mutex to Monitor, the errors disappeared. Can you please 
commit the same change (apart from fixing my issue, I can't see any harm)

Thank you,
Ittay
