os/signal: tests run too long and fail on NetBSD

[bradfitz]

The new NetBSD 7.0 builders on GCE are now up and we're trying to get the build passing on NetBSD again.

The latest failure is:

*** Test killed: ran too long (4m0s).
FAIL	os/signal	273.238s

@ianlancetaylor, Mr. Signals, any ideas?

/cc @bsiegert @mdempsky

[ianlancetaylor]

No ideas. Are they gomote-able?

[bradfitz]

Yes.

[bsiegert]

The last time this came up was #16511, though that was on 32-bit.

[bradfitz]

I updated the NetBSD builders to NetBSD 7.1.

Maybe something was fixed. We'll see.

[zoulasc]

Should be fixed in NetBSD head and with the latest netbsd package from pkgsrc.

[bradfitz]

Our continuous build system uses Go's source, not pkgsrc.

Were there NetBSD kernel fixes involved? (That is, do we need to update our base VM Image and update Go's https://golang.org/wiki/MinimumRequirements page to say you need NetBSD 7.2?

[gopherbot]

CL https://golang.org/cl/41350 mentions this issue.

[krytarowski]

I guess that NetBSD 8-beta is sane minimum.
