[Qt-interest] Problems with QSslSocket hanging

[Thomas Dähling]

Isn't Qt using OpenSsl? I remember that OpenSsl uses Heap32Next()
which used to return in constant time before Win7 but with Win7 it is
depending upon the amount of objects allocated on the heap. This can
even trigger the problem that the SSL connection times out. Not sure
if OpenSSL fixed this yet, though. Tried checking but their website is
down for me at the moment... one way or another, according to Google
this is the link to the issue:
http://rt.openssl.org/Ticket/Display.html?id=2100&user=guest&pass=guest
