[Lazarus] IDE unstable - Online Package manager bug

[Martin Frb]

So it hangs in openssl.
Which means the http request can not be aborted. (gracefully)

How up to date is your openssl?

I recently had an issue with git on windows, due to an openssl bug 
https://github.com/git-for-windows/git/issues/1993

The openssl bug seems older, but some activity referring to a fix is 
very recent.
So just maybe...?

--------------------
It might be possible to limit the IDE wait time though. Since this is on 
shutdown, the IDE can wait with the thread still running. That would 
report a memory leak.... (but not a problem, since it is a one off / 
will not accumulate)

That is assuming the OS manages to kill the thread then.
On windows it was not possible to kill any app hanging in that openssl 
bug (A system restart was required)
