I'm wondering how thread-safe POSIX calls like open(), connect(), read(), etc. are on OSX versions, specifically 10.3.9, 10.4.x, 10.5.x and 10.6.x?

These interfaces are thread-safe by most definitions. It is OK for multiple threads to be making these calls simultaneously. However, it is up to the application to ensure data integrity; using these calls with the same file descriptor on multiple threads simultaneously will yield unpredictable results.
