Fixed a bug where a fun's environment could be overridden by an argument if all of the following conditions were met:

-- The fun was declared in the module that called it.

-- The fun's target was statically known.

-- The fun was called with a number of extra arguments equal to the number of environment variables.

Fixed a more or less harmless bug that caused time correction of Erlang monotonic time to become slightly off on Windows platforms when QueryPerformanceCounter() was used as OS monotonic time source.

erlang:system_info(os_monotonic_time_source) now also returns information about used resolution which not always corresponds to the resolution of the OS monotonic time source.

Checks for monotonicity of monotonic time have been improved so that Erlang and OS monotonic time are checked separately.

A new configure argument --enable-ensure-os-monotonic-time has also been added. It enables functionality ensuring the monotonicity of monotonic timestamps delivered by the OS. When a non-monotonic timestamp is detected, it will be replaced by the last delivered monotonic timestamp before being used by Erlang's time functionality. Note that you do not want to enable this unless the OS monotonic time source on the system fails to produce monotonic timestamps. This since ensuring the monotonicity of OS monotonic timestamps will hurt scalability and performance of the system.
