<<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?
For example, reading or writing a file.
There is no specific thread-safety code in libtiff. The code is written to be re-entrant but there are still some static variables.
On some systems, it is necessary to build code with particular options in order to be thread safe (e.g. C library functions may otherwise not be thread safe). Libtiff does not (by itself) provide any such build options.
