Hi Bob,

Thank you for responding.

<<a bunch of threads requested to open different TIFF files all at the same
time>>
This is exactly my case

<<the library has been exercised at least once>> What do you mean by exercised?

Thank you,
Katerina

That said, it is hopefully safe for different threads to operate on distinct TIFF objects at the same time.

There are some areas related to library initialization and error reporting which do not appear to be thread safe. If a bunch of threads requested to open different TIFF files all at the same time before the library has been exercised at least once, then failure is likely.
