.... or not regession, that's the question.

2.6.16-rc2 works without problems.

With -rc3 a .swf that opens a ip connection back to the server takes ages to
load. strace shows that the player hangs for long times in select().

Digging through the changelog brings up

----------------------

fixed that, the player works again in normal speed.

The player is the newest from macromedia (7.0.61.0, gentoo ebuild), binary
only of course:( Reading the patch and the documentation of select() i think
the player is buggy... but works until 2.6.16-rc3

So what is your opinion? I think, macromedia should fix the player...

Thanks
