Is WorkAroundNPTLTimedWaitHang safe to disable?

There is a Linux-specific VM product flag, WorkAroundNPTLTimedWaitHang.
The comments in src/share/vm/runtime/globals.hpp describe the flag as 

	(Unstable, Linux-specific) "avoid NPTL-FUTEX hang

Would this be a workaround for this issue?

In any case, are there are guidelines for safely disabling this workaround?
Guidelines, e.g. libc version, vendor.kernel.version, et cetera.

Many thanks,
