If I run a particular trace for an event I expect to be trigger very often (say expected 1000Hz) then as soon as magic trace starts recording, it stops. As a consequence I get a very limited history.

While my software trigger could be written to only probabalistically trigger I'd like it if magic trace had an option "refuse to trigger until we've been recording for TIME-SPAN".

Add -min-trigger-time to delay installing breakpoint
c846898 
This allows capturing traces with `-trigger` symbols that get called
with very high (possibly bursty) frequency, where we otherwise migt
trigger before the snapshot buffer has a chance to fill up.

Closes janestreet#56.
