hmm sockets (again)

Hey all, Just looked through the changelog for 4.0.5 and was suprised to see that the socket functions had not been fixed, (set_nonblock does not seem to work under linux), I have retried my scripts under the new version but nothing seems to have changed, For the time being I am going back to the network and filesystem functions which do seem to be more reliable now. I am a little confused though,about the following extracted from the changelog:

Fixed a compatibility problem in some file functions (fgets, fputs, fread, fwrite). The ANSI standard says that if a file is opened in read/write mode, fseek() should be called before switching from reading to writing and vice versa.

How does this affect calls to a fsockopen? Can anybody else can confirm that set_nonblock() is indeed broken. If it is I will make sure that the bug is reported. Regards, Joseph
