happens & Vim uses 100% of the CPU, you can attach with gdb to the
Vim process that hogs the CPU, and look at the stack trace. That may
give useful information to debug it.
(gdb) attach pid
(where pid is he process ID of the Vim process using 100% of the CPU)
You can then continue with...
... and press CTRL-C in gdb to stop vim and run bt again to see if you
get similar stack trace. You can repeat that a few times to get a feeling
of what Vim is doing.
