Rigol MSO5074 crashes when we try to do stuff with glscopeclient

[kench]

I need to include packet captures, but both the scope and glscopehal become unresponsive.

Possibly related to #146.

To avoid overlap, this ticket is specifically for the scope firmware hanging, not glscopeclient.

Degi was able to reproduce the crash with this short code snippet: http://paste.debian.net/1165913/

I cannot reproduce that issue with my Rigol MSO5074 (HW 01.01.00) and latest firmware 01.03.00.01
Anyway so far on windows glscopeclient is unusable with something less than 1 frame per second...

Believed fixed with latest Rigol firmware.
