This code segfaults for me. Could be related to #3904, not sure.

I expected the following

No segfault

Looks very similar to #3904

They need to be removed from the socket hash linked list with more care.

When sh_delentry() is called to remove a sockethash entry, remove all
individual transfers from the list first. To enable this, each Curl_easy struct
now stores a pointer to the sockethash entry to know how to remove itself.
