This would be useful for Windows.  There is some information which would
be useful to know about a thread but there is currently no way to
display it.

When I added thread support for Windows I wished for an additional field
or two in gdb's thread structure which would have allowed me to store
extra OS specific state about a thread.  It would only have to be an
opaque void * pointer of use only to the target.  This would have saved
a fair amount of head-standing in win32-nat.c.

But, I don't think that this is exactly what you're talking about.
Having some kind of extensible way to query and report thread
information would be nice.  At the very simplest an additional target
vector could be supplied which returned extra information to tack onto
info thread output.
