57	Dynamic libraries cannot be freed when sockets (at least) are used	Yuri Dario	bird	"When a dll uses a socket function (but not only in this case), the dll cannot be unloaded by DosFreeModule(), usually rc=12 (ERROR_INVALID_ACCESS) is returned. This leaves the dll file locked by the process, and it can be replaced only after process end (unlocking the dll is not enough, the current process will still use the old dll).

Sample code included in the attachment (source and binaries).
