panic: dsched: malloc limit exceeded

[Steve O'Hara-Smith]

	Hi,

	I can reproduce the panic above quite easily - just doing a pkgsrc
build of my selected packages does the job - somewhere in the perl build.

	System is built from a recent master
v2.7.3.1084.g7b033-DEVELOPMENT, running on a Phenom II 955 in an M4A78L-M
motherboard with 4GB of memory, a 32GB SSD providing an 8GB root and 2 8GB
swap partitions (with swapcache enabled) and a pair of terabyte drives in
vinum based RAID1 holding a 50GB UFS partition and the rest Hammer. The
package build was taking place in a chroot on the 50GB UFS partition.
