deadlock on flt_noram5

[manu%netbsd.org@localhost (Emmanuel Dreyfus)]

Hi

I experience kernel hangs, which seems to be related to memory getting scarce.
getty on console is unresponsive, but I least I can drop into ddb. 

db> ps
PID    LID S CPU     FLAGS       STRUCT LWP *               NAME WAIT
27030    1 3   0         4           cbc6fa80               cron flt_noram5

24643    1 3   0         4           cbc6f300                 ld flt_noram5

(...)
229      1 3   0         4           cac4f580           perfused flt_noram5

Reading the sources, it seems that we sleep on flt_noram5 when we are out of
memory, but that nothing in the kernel is there to awake us from flt_noram5,
both on -current and netbsd-5

Is that a known problem?
