This adds a -j parameter which writes traces of your Urbit's function call
stack to a json file, readable by Chrome's about://tracing or the standalone
trace-viewer webapp.
Everytime a new road is constructed, a new bank of cells is
allocated and initialized. This lead to over three megabytes of
memory being allocated and accessed on each road change. This takes
more than 1ms to complete.
Road changes occur on each virtualization call. Each +soft happens
virtualized; so each +soft call incurs a 1ms delay. The metavase
machinery does at least two (and usually three) softs per card move
meaning sending a card move through arvo usually incurs a 3ms delay.
Before this patch, the following line took six seconds to execute.
Now it is imperceivable:
```
~:(turn (gulf 0 10.000) |=(a=@ud (mule |.(a))))
```
if the warm dashboard is reaped before call sites, the activation
(and thus the label inside the activation) can be freed (during u3h_put)
while a call site in the junior still points to the label (but doesn't hold
a reference to it, since it is on a senior road). trying to take that label
during call site reap then results in a bail: foul.
the solution is to always reap call sites before reaping the warm dashboard.
