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.
