Description

Review and cleanup of mutexes in timezones.

There is a race in the initialization of TZDATA_VERSION. The first byte of the string is being used as the flag to indicate that it has been initialized. A second thread could potentially see the string with the first byte set, but with less than the full string set.

Also are places where mutexes are being held longer than they need to be.
