Some info from IRC:

<ggaren> aroben: what is the value of m_operationInProgress?
<aroben> ggaren: NoOperation
<ggaren> aroben: what are m_globalData->m_refCount and m_globalData->dynamicGlobalObject?
<aroben> ggaren: 2 and 0x022a0128
<ggaren> aroben: and is m_globalData->m_deletionHasBegun false?
<aroben> ggaren: yes
<ggaren> aroben: inside main, what is the value of res?
<aroben> ggaren: 3
<ggaren> aroben: i have a guess that res was set to 3 by the TRY / EXCEPT clause. if so, we've caught the bug too late.
<aroben> ggaren: makes sense
<aroben> ggaren: I can remove the try/except
<aroben> ggaren: I see a comment that say try/except is only there to block the normal crash report mechanisms
<aroben> ggaren: seems like eventually we'd like to save crash logs instead of just using a magic 3 return code
<ggaren> aroben: inside jsc, all access (save 1 irrelevant place) to dynamicGlobalObject is managed by an RAII object: DynamicGlobalObjectScope. so, now i'm even more sure of my guess.
