tst_qquicktextedit crash on vxworks SR650 randomly

Platform: VxWorks 7 SR650 clang

Randomly crashes on testcase where network is used.

 Happens at least in tests:

void tst_qquicktextedit::embeddedImages()

tst_qquicktextedit::cursorDelegate()

Reason seems to be that those use network, but cause if whole network interface kernel task crash is unclear.
