[htop-general] [RFC Patch] Display thread name

[Loke, C. <Che...@ne...>]

Hello Hisham and others,

I would like htop to display thread names. May be such an option exists
already. If so, then please ignore this email.
I saw that ProcessList_processEntries:: has a #HAVE_VSERVER that does
something similar?
Anyways, I've attached a patch.

I could have reset my local svn head to revert back to the 0.8.2 rev but
I just unrolled the 0.8.2 tarball because that's what we are using.

Please consider to apply.

Regards
Chetan Loke

------------------------------------------------

Added support for displaying thread name(set by prctl et al) by grep'ing
status proc-file.

The patch was generated against the 0.8.2 version

Tested on my linux host.
