non-sleepable locks in kern_fork.c

I'm seeing this way WAY too many times as of last night's CTM deltas (Central Standard Time):

malloc() of "256" with the following non-sleepable locks held:
exclusive sleep mutex filedesc structure r = 0 (0xc3a54a38) locked _at_ /src/sys/kern/kern_fork.c:421

I built+installed world & kernel etc. as usual.

I'm pressed for time right now; I'll need to go back to the previous kernel and continue looking at this on Monday.  Maybe by then s'more patches will come out to fix it.  ;)

(I use MacOSX at home, no li'l-endian machines there at all ;)

Thanks,
