Hey @Yogu
Sorry it took so long to get back to you... I started reviewing your change and then... somehow forgot about all this! Ehcache3 is taking up pretty much all of our attentions...
Anyways, there are a bunch of issues with the changeset as it stands (race conditions, wrong interrupt handling, ... most importantly missing tests). But given how long it took me to get back to you, how would you rather go about this?

• Should I comment on the PR?
• Work a bit on that changeset on my own fork and discuss it further from there?
• Some other option?

I understand this isn't probably fresh in your head at all anymore, so let me know how you'd best go about merging this in, and I'll act accordingly!
Again, sorry for having let this sit so long!
Alex
