Comment (by Ion Gaztañaga):

 I can't see any sensible fix, synchronized_pool_resourc is not thought to
 be prepared to handle priority inversion and several platforms don't
 support something like PTHREAD_PRIO_INHERIT and the default pthread
 implementation might not support priority inheritance protocol. I don't
 know if also setting this flag can affect performance for the common case.

 Maybe you should build the library using USE_SPIN_LOCKS=0 and this should
 be at least documented.
