Curl: travis coverage build hangs

[MarcelRaad]

I did this

Since either https://github.com/curl/curl/commit/8581e1928ea8e125021408ec071fcedb0276c7fe (canceled) or https://github.com/curl/curl/commit/2f11fbf208c78d38e9a19b1224238c4ecff5989f (failed), coverage builds are failing because No output has been received in the last 10m0s after event-based test 0089...[HTTP with NTLM and follow-location].
See https://travis-ci.org/curl/curl/builds and https://coveralls.io/github/curl/curl.

I expected the following

The job to succeed.

operating system

Ubuntu Xenial on Travis

I've restarted the canceled coverage build:
https://travis-ci.org/curl/curl/jobs/538157881
Also trying to reproduce locally.

The restarted build failed with the same error, so the culprit seems to be https://github.com/curl/curl/commit/8581e1928ea8e125021408ec071fcedb0276c7fe.

3997 is supposedly the medicine for that too...

[MarcelRaad]

Ah, yes, the coverage build there was successful now!

I can confirm that current master still fails (I thought that https://github.com/curl/curl/commit/680f1413321c0bad593a69a86511df4d98a3b5df might have fixed it as it only occurs in the event-based test) and https://github.com/curl/curl/pull/3997 fixes it!
