SpinLockAcquire question

Hi,

is there a danger in using SpinLockAcquire() in
a signal handler? I mean if e.g. a spinlock is already
taken by the process and a signal comes that's handler
wants to execute SpinLockAcquire() again, does it
lock up or simply increases the lock counter?

Thanks in advance,
Zolt�n B�sz�rm�nyi
