sbcl/stumpwm crashes when using slime/swank

[Joseph Mingrone]

The SBCL image included with StumpWM is quite stable without slime/swank. With slime/swank on, crashes eventually happen. They seem related to calling external shell scripts. Here is an example backtrace:

Unhandled memory fault at #xE.
   [Condition of type SB-SYS:MEMORY-FAULT-ERROR]

Restarts:
 0: [REMOVE-FD-HANDLER] Remove #<SB-IMPL::HANDLER INPUT on descriptor 4: #<RESTART <<error printing restart>> {1006CFD393}>

I forgot to mention I'm using sbcl-1.2.8 on FreeBSD 10.1 amd64.
