Attempted repro

So far, no luck trying to repro by:

open connection
assign versionchange handler (w/o connection reference in closure)
drop all references
force GC
open second connection

At this point I see:
* the versionchange handler fire (which would seem to indicate that my GCing was unsuccessful)
* an arbitrarily long pause (up to 20 seconds?); pause can be shortened (in chrome) by opening the inspector. Presumably this is waiting for an actual GC.
* the second connection opens successfully, indicating that the first connection was finally closed
