[webkit-help] question about ThreadIdentifierData::m_key

[yuqing cai]

hi, all.
in the file WebKit/Source/WTF/wtf/ThreadIdentifierDataPthreads.cpp, the
variable "ThreadIdentifierData::m_key" is initialized to be
"PTHREAD_KEYS_MAX", in this case, why function
"ThreadIdentifierData::identifier()" try to ASSERT it? the ASSERTION
seems always FAILED.
my question is why ThreadIdentifierData::m_key is initialized to be
"PTHREAD_KEYS_MAX"?
