Probably, as mach uses new allocator now, this bug could be closed?

That's a general issue with leaks of port & such.  In the debian
gnumach package I've extended the zone map to 64MB. On buildds, I've
actually even made it 200MB.

I got this panic twice now:

panic: zalloc: zone kalloc.8192 exhausted

from the Mach kdb trace:

root@beethoven:/mnt/boot # addr2line -f -e gnumach-dbg 0x119127
root@beethoven:/mnt/boot # addr2line -f -e gnumach-dbg 0x1190fe
root@beethoven:/mnt/boot # addr2line -f -e gnumach-dbg 0x123ee0
root@beethoven:/mnt/boot # addr2line -f -e gnumach-dbg 0x11b66a
root@beethoven:/mnt/boot # addr2line -f -e gnumach-dbg 0x11a548
root@beethoven:/mnt/boot # addr2line -f -e gnumach-dbg 0x14aed5
root@beethoven:/mnt/boot #

This time, a mysql build aborted with the following error message:

libtool: link: `libtaocrypt_la-aestables.lo' is not a valid libtool object
make[5]: *** [libtaocrypt.la] Error 1

After killing off the build processes and restarting another build, the machine was becoming quite sluggish and Mach paniced quite soon thereafter with the above zalloc exhausted message.
