[Swift-devel] lots of variable not found

[Ben Clifford]

I've seen these sporadically in the past but there seem to be more of them 
happening in the nmi build and test recently.

On 
http://nmi-s005.cs.wisc.edu:80/nmi/index.php?page=results/runDetails&runid=140131
the 066-many test fails with 

Progress:  Selecting site:1021 Active:1 Stage out:1 Finished 
successfully:1596
Execution failed:
	Variable not found: #channel#restartout

and again in here:
http://nmi-s005.cs.wisc.edu:80/nmi/index.php?page=results/runDetails&rows=20&&runid=140127&offset=20&rows=20
on nmi_cent_4.2 
and a 

Progress:  Selecting site:1021 Active:1 Stage out:1 Finished 
successfully:1867
Execution failed:
	Variable not found: #threadcount

in 066-many on x86_suse_10 in that same URL above.

I've also seen:

  Event was No #caller found on stack for sys:sequential @ 066-many.kml, 
  line: 35

on NMI's x85_slf_3 platform, again in 066-many.

These all have the feel of something racy in Karajan, and are hopefully 
relatively easy to reproduce (i.e. run 066-many tens of times and you 
should get).

On the jdk 1.4 test that ran last night, 3 out of the 13 runs that have 
completed as of my writing this mail failed. Thats over 20% which is an 
uncomfortably high failure rate.
