core dumps being overwritten

[Alexander Best]

after a panic and a core dump i was quite surprised to see that one of my
previous core dumps got overwritten.  is this behaviour controlled by a sysctl
parameter and has changed recently? i had the following contents in
/var/crash:

bounds
core.txt.0
core.txt.1
core.txt.2
info.0
info.1
info.2
minfree
vmcore.0
vmcore.1
vmcore.2

after a panic and core dump core.txt.1, info.1 and vmcore.1 got replaced.

i'm running r195712 (8.0-BETA2).
