---------- Legend --------------------------------------------------
n-i-bz = not in bugzilla
pending = is scheduled to be fixed (or at least considered) on this branch
wontfix = will not fix on this branch
many = fix composed of many commits
WF = waiting for feedback from bug reporter
PRI: 33 = fix this for 3.3.1
Vfd = fix has been verified on 3.3.X branch
*** definitely fix
### merge fix to 3.3 branch
??? marginal
NNN won't fix
Vfd fix has been verified on 3.3.X branch
Fxd fixed
---------- Bugs reported after (in) 3.3.1 --------------------------
LOW/MED/HIGH describe impact of bug
HIGH - major loss of functionality, no workaround
MED - loss of functionality, not critical or workaround possible
LOW - minor incorrectness, ought-to-fix etc
re Keller vpath bug, don't use attached patch; use Ashley's one
instead (on @dev ?)

(no test case)
160595 Wont pend Why my program hang-up when work with valgrind ?
(no info so far, probably a threading bug in client)
