No, I don't think so, at least not because of the shared environment. 
Generally (always?) in a shared environment you first have to tell the 
other device to completely stop accessing the flash. Once you start any 
operation other than read then you cannot have anything else access that 
flash device or else one or the other will get corrupted results eg ID 
instead of code fetch. So the best thing to do is to complete all 
operations as quickly as possible and then signal the shared accesses to 
resume.
